Question

A body falls for 5 s from rest. If the accele-
ration due to gravity of earth ceases to act, the
distance it travels in the next 3 s is



plz give answer
dont give unnecessary answers plz​

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+
