Question

. A punter in a football game kicks the ball with an initial speed of 28.3 m/s at an angle of 60° with respect to the
ground. The ball is in the air for a total of 5.00 s before hitting the ground. If we assume that air resistance is
negligible, what would be the ball's horizontal displacement?
(A) 0 m (B) 14.2 m (C) 24.5 m (D) 70.8 m (E) 122.5 m

Answer 1

Explanation:

$u \cos( \alpha ) constant \: in \: proectile \: motion$

if

$\alpha = 60degree$

$28.3 \times \cos(60) \times t = horizontal \: displacement$

so answer is 70.8
