Question

A body takes 5 second to travel 80 m in a certain planet .Calculate the acc due to gravity on that plane​

Answer 1

Answer:

Initially the body starts its motion from rest therefore u=0. Let journey be A when a acceleration of earth is acting on the body time =5 seconds let's find v

v=u+at

=0+9.8×5=49m/s

When acceleration stops acting the velocity of the body is 49m/s. Now the distance traveled by the body in next 3s

S=ut+
