Question

A child kicks a ball horizontally with a speed of 5m/s off deck 25m off the ground . How far from the deck does the ball land on the ground?

Answer 1

to vertical direction, \(V_0 =0\) apply \(h = h_0 + V_0t+ 1/2 gt^2\) to find out the time t
then, to horizontal direction, \(V_0 = 5m/s) apply \(S =S_0 + V_0t + 1/2at^2\) where a =0, \(S_0 =0\) and t from the vertical part to find out S
