Question

a boy standing on the tray of a utility travelling at 5 ms throws aa ball vertically upwads with a velocity of 7.35ms (relative to himself) and catches it again at the same level. what horizontal distance does the ball move while it is in the air

Answer 1

Vo = 5 + i7.35 = 8.89m/s[55.8o]

Dx = Vo^2*sin(2A)/g
Dx = 8.89^2*sin(111.6)/9.8 = 7.5 m.
