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.

Correct answer choice is :

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

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.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
