Question

A golf ball is hit into the air, but NOT Staight Up, and encounters no significant air resistance. Which statement accurately describes its motion while it is in air? On the way up, both its horizontal and vertical velocity components are decreasing, on the way down they are both increasing. Its acceleration is zero at the highest point. Its horizontal velocity doesn't change once it is in air, but its vertical velocity does change. On the way up its acceleration is 9.8m/s2 upward, on the way down its acceleration is 9.8m/s2 downward, Its velocity is zero at the highest point.

Step-by-step explanation:

A) False , horizontal velocity component is constant since there's no horizontal acceleration component

B) False, acceleration remains constant through out and only verticle acceleration is there horizontal acceleration is zero.

C) True , Its horizontal velocity doesn't change once it is in air, but its vertical velocity does change ( because of acceleration in verticle direction)

D)False, the acceleration is constant through the motion.

E)False, Vertical velocity is Zero but there will be Horizontal velocity.
