Ryan rolls a steel ball horizonyally at 0.8m/s from a top of a lab table that is 0.95 m high.

a) How long will it take the stone to strike the ground?

b) How far from the edge of the table did the ball travel?

For part a we can use the kinematic formula distance = velocity (initial) * time+1/2*acceleration*time^2

we know there is only velocity in the horizontal and none in the vertical so v initial in this case is 0, acceleration is gravity = 9.81m/s^2

plug in. 95 = (1/2) * 9.81*t^2 solve for t

t=.44seconds

Now for part b we know there is no horizontal acceleration so distance = velcoity * time

we will use horrizontial velocity and the time we just found

distance =.8m/s*.44seconds

=.35 meters
