Question

Barry is conducting an experiment and rolls a tennis ball down a ramp. Which best describes the motion of the tennis ball?

A.) It does not exhibit projectile motion and follows a straight path down the ramp.

B.) It does not exhibit projectile motion and follows a parabolic path down the ramp.

C.) It exhibits projectile motion and follows a straight path down the ramp.

D.) It exhibits projectile motion and follows a parabolic path down the ramp.

Answer 1

Answer: A) It does not exhibit projectile motion and follows a straight path down the ramp.

Step-by-step explanation:

A ramp is an inclined surface which lifted from the ground at certain angle. Motion of an object down an inclined plane follows a straight line path. It does not exhibit a projectile motion because a projectile is thrown on the surface of the Earth at an angle and the object falls under the influence of gravity only.

In an experiment when Barry rolls a tennis boll down a ramp, it would follow a straight line path. The ball would slide down the ramp due to gravitational pull. Frictional force between the surface of the ramp and ball would act in opposite direction. The ball would also exhibit rolling motion. Hence, the correct option is A.

Answer 2

Correct answer choice is :

A) It does not exhibit projectile motion and follows a straight path down the ramp.

Step-by-step explanation:

An inclined plane, also identified as a ramp, is a flat promoting surface turned at an angle, with one end higher than the other, applied as an aid for increasing or reducing a load. The force of gravity looks straight down, but a ball rolling down a slope doesn't go straight down, it reflects the ramp. Therefore, only the element of the gravitational force which leads along the path of the ball's motion can stimulate the ball.
