Question

You throw a rock off the top of a building located on the Planet Mars with an initial velocity of 10.0 m/s. The force of gravity on Mars is ⅓ that of Earth. It takes 12.0 s to hit the ground. How tall is the

building? please help!

Answer 1

u=10m/s
acceleration due to gravity=9.8/3=3.27m/s^2
t=12s

s=ut+1/2at^2
s=10(12)+1/2(3.27)(12)^2
s=355.2m
