Question

11 How far away does a ball land that rolls off a 2 m high table rolling at 9 m/s

a) 5.75 m
b) 10.25 m
c) 13.75 m/s
d) none of the above

*Please Show Equation*
Thank You!

Answer 1

H = 1/2 g t^2 time to fall H

t = (2 H / g)^12 = (2 * 2 / 9.80)^1/2 = .639 sec

Sx = Vx * t = 9 m/s * .639 s = 5.75 m horizontal distance traveled
