Question

A ball rolls off the edge of a 0.75m high lab table with a horizontal speed of 1.50 m/s. Calculate the time that the ball is in flight, calculate the vertical velocity of the ball just before striking the floor, and calculate the horizontal distance(range) that the ball will travel.

Answer 1

h = 0.5g*t^2
g = 9.8 m/s^2.
h = 0.75 m.
Solve for t(Fall time).

V^2 = Vo^2 + 2g*h
Vo = 0
Solve for V.

Dx = Xo*t
Xo = 1.50 m/s
t = Fall time.
Solve for Dx
