Suppose you are an astronaut and you have been stationed on a distant planet. You would like to find the acceleration due to the gravitational force on this planet so you devise an experiment. You throw a rock up in the air with an initial velocity of 11 m/s and use a stopwatch to record the time it takes to hit the ground. If it takes 5.4 s for the rock to return to the same location from which it was released, what is the acceleration due to gravity on the planet?

Answer:
4.07 m/s^2

Step-by-step explanation:

Given

time taken= 5.4 s

Velocity=11 m/s

let t be the time taken in earth

therefore


t=(2v)/(g)=(2* 11)/(9.8)=2.24 s---1

In distant planet


t'=(2v)/(g')


g'=(2v)/(t')=(2* 11)/(5.4)=4.07 m/s^2
