Question

When initial velocity is increased, what happens early in the flight of a golf ball?

A) There is a greater upwards acceleration and less slowing down of the ball

B) There is a greater downwards acceleration and less slowing down of the ball

C) There is a greater upwards acceleration and more slowing down of the ball

D) There is a greater downwards acceleration and more slowing down of the ball

Answer 1

When a golf ball is hit with a increased initial velocity, it follows a projectile motion ( parabolic path ).

The maximum height reached and the horizontal distance that the ball will travel will be proportional to square of the initial velocity.

As the initial velocity will increase in the early half of the path so its vertical component of the acceleration will act upward and will continously increase till it reaches the maximum point, where its velocity will be zero.

So, the correct option will be C.

There is a greater upwards acceleration and more slowing down of the ball
