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

Shane Gilbert · Answer 2

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

Explanation:

Projectile motion is the motion of the object that is projected into air. The only force acting on it must be the earth's gravity. The object projected into air is called the projectile and its path is called the trajectory.

In our case Barry is not throwing the tennis ball into air. It is just moving along the surface. It is just like any other movement on a flat surface The only difference it is happening at an angle.

In our case there is friction acting on the tennis ball, but only earth's gravity is supposed to act on the tennis ball.

So it does not exhibit projectile motion and follows a straight line path down the ramp
