Question

A ball rolls off a horizontal table 1 m high with a velocity of 3 m/s. Find:
a.) The time before the ball strikes the floor
b.) The horizontal distance of the ball from the foot of the table

Answer 1

the direction of initial velocity is x

Answer 2

so the vertical movement is free fall with the initial velocity 0m/s
equation：Y: \[1/2\times g \times t ^{2} =1m\]

Answer 3

Rearrange haijon's expression to find the time of flight. and then use x=vt with v=3 and the time you've previously solved for to find the horizontal distance.

Answer 4

t=\[\sqrt{2h/g}\]
h=1m
g=9.8 m/\[s ^{2}\]
