Question

Can I please just have a anwser instead of a whole explanation

Answer 1

The prediction made by Wilbur about the distance being affected when the force applied to a race car is changed is correct. So, the right answer is option (c).

Yes, the force applied to the car indeed affects the motion.

Answer 2

Given,

Wilbur's prediction is that changing the force applied to a car would affect the distance it travels.

From Newton's second law, Force applied on an object is equal to the product of the mass of the object and the acceleration produced due to the applied force.

That is,

`F=ma`

Thus changing the applied force will change the acceleration of the object when the mass of the object is constant.

Thus, if the force applied to a car is increased the car will accelerate at a higher rate. And when the force applied to a car will increase the car will accelerate at a lower rate. If the direction of the force is changed the car will decelerate.

Thus the force applied to a car will affect the distance and the motion.

Therefore, the correct answer is option 3.
