Throw a rock horizontally at 22 m/s from a 315 m tall building. How far from the base of the building will it land?​
creativ13 [48]

Answer:

176.44 m

Explanation:

y = (vertical vi)t + (1/2)gt^2

315 = 0 + (1/2)(9.8)t^2

t = 8.02s

x = (horizontal vi)t + (1/2)at^2

x = (22)(8.02) + 0

x = 176.44 m
