Question

a body falls for 5s from rest .if the acceleration due to gravity of earth ceases to act the distance it travels in the next 3s

Answer 1

Hey!

Time for it falls = 5s
Acceleration due to gravity = 10 m/s^2
Initial velocity (u) = 0
Final velocity (v) = ?

v= at+u
v= 10×5
v= 50 m/s

Distance travelled in next 3s without acceleration due tp gravity = Speed × Time

Distance = 50×3
Distance = 150 m


Hope it helps ...!!!

Answer 2

Answer:

147m

Explanation:

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+1/2gt² =49×3

=49×3

=147m.
