Question

A ball is thrown from the top of a cliff. The initial magnitude of the velocity of the ball at time t=0 is V. The ball hits the sea at time t=T. Air resistance is negligible.

Which graph shows how the vertical component of the velocity v of the ball varies with t as it falls to the sea?

Markscheme

D

Examiners report

Although the ball is launched with a velocity of V, the question refers to the vertical component. Therefore, the initial velocity in the vertical direction must be less than this value. Many candidates failed to pick up on this point.
