The difference of two numbers is 28. Find the number if the larger is 3 times smaller.​

Answers

Answer 1

Answer:

14,42

Explanation:

Let the smaller number be x

Hence, the larger number = 3x

Hence,

[tex]3x-x=28\\2x=28\\x=14[/tex]

Hence, the smaller number = x = 14

The larger number = 3x = 42

A student is standing on a very steep hill, kicks a soccer ball horizontally with a speed of 10 m/s toward a student who is sitting on a level field 3 meters below. How long does it take the soccer ball to strike the ground?

Answers

Answer:

0.782 seconds

Explanation:

We are given that the ball starts out on a hill that is 3 m above a level field below. And that the ball is kicked horizontally. We are asked how long the ball takes to hit the ground 3 meters below.

On closer consideration of the given situation, it is important to realize that even though the ball starts out with a speed of 10m/s in the horizontal direction, that this will not make a difference in how fast the ball travels in the vertical direction (which is what the question is basically asking for). Hence for this question, we can ignore the initial horizontal speed of the ball and realize that the initial vertical speed is 0 m/s.

Recall that one of the equations of motion can be expressed as:

s = ut + (1/2) at²       (refer to attached for reference)

where,

Applied in the vertical direction,

s = vertical distance travelled = 3 meters in this case

u = initial vertical velocity = 0 m/s in this case

a = acceleration due to gravity, g = 9.81 m/s²

t = time taken ( we are asked to find this)

simply substituting the known values above into the equation:

s = ut + (1/2) at²

3 = 0 + (1/2) (9.81)t²

3 = 4.905t²

t² = 3 / 4.905

t² = 0.61162

t = √0.61162

t = 0.782 seconds

Problem
Position The figure shows a motorcyclist traveling east along a straight
road. After passing point B, the cyclist continues to travel at an average
velocity of 18 m/s east and arrives at point C2.8 s later. What is the
position of point ?

Answers

Answer:

s = 50.4 m

Hence, the point C is 50.4 m towards east from point B

Explanation:

Since, the motorcyclist travels at a constant speed in straight line towards east after point B. Therefore, we can use the following equation in this case:

s = vt

where,

s = distance covered = position of point C = ?

v = uniform speed of motorcyclist = 18 m/s

t = time interval = 2.8 s

Therefore,

s = (18 m/s)(2.8 s)

s = 50.4 m

Hence, the point C is 50.4 m towards east from point B

A 1.11km

B 3.08km

C 0.32km

D 1.85km

Answers

Answer:

The answer is option A

Explanation:

In order to find the distance covered we use the formula

distance = velocity × time

From the question

velocity = 1.85 km/hr

time = 0.6 hours

We have

distance = 1.85 × 0.6

We have the final answer as

1.11 km

The chemical properties of elements are those properties that are noticeable during the course of a chemical reaction.

Aluminum is solid but not at room temperature. The elements that are solid at room temperature are iron, zinc, gold, and silver. Hence option is incorrect.  The same is applicable to options B and C.

The force needed to stop an object in motion is called?

Answers

force called friction

The force applied to object to stop its motion is known as frictional force.

Newton's first law of motion states that an object in a state of rest or uniform motion in a straight line, we continue in that form unless it is acted upon by an external force. This reluctance of an object to move or stop moving is known as the object's inertia. This inertia depends on the mass of the object.

When an object is finally in motion, the friction, between the object and the surface on which it is moving tends to limit the motion.

Thus, to stop an object in motion, we increase the frictional force between the object and the surface on which the object is moving

1. A skateboarder is skating over a circular bump. He is at the top of the bump and is
moving rightward. Is the normal force exerted on the skateboarder by the bump greater
than, less than, or equal to the weight of the skateboarder? Explain your reasoning.

Answers

Answer:

The normal force exerted on the skateboarder by the bump is less than the weight of the skateboarder

Explanation:

The given parameters are;

The location of the skateboarder = The top of the circular bump

The direction of motion of the skateboarder = Rightward

Therefore, given than the skateboarder has both horizontal angular motion (moving rightward) and vertical angular motion (over the bump), The effect of the weight of the skateboarder on the ground is reduced by the centripetal forces acting on the skateboarder and the normal force exerted on the skateboarder by the bump is equal to the reduced weight and is therefore less than the actual weight of the skateboarder.

The normal force exerted on the skateboarder is less than the weight due to the effect of centripetal force.

Given data:

The position of skateboarder is at top of the circular bump.

And direction of motion of Skateboarder is towards rightward.

Since, the skateboarder is undergoing the motion over the circular path, then it will have both horizontal angular motion (moving rightward) and vertical angular motion (over the bump).

The effect of the weight of the skateboarder on the ground is reduced by the centripetal forces acting on the skateboarder and the normal force exerted on the skateboarder by the bump is equal to the reduced weight and is therefore less than the actual weight of the skateboarder.

Thus, we can conclude that the normal force exerted on the skateboarder is less than the weight due to the effect of centripetal force.
