Question

a body having a mass of 100 grams is allowed to fall freely under the action of gravity.what is its kinetic energy after 10 seconds
$g = 1000cm \: s {}^{ - 2}$

Answer 1

ASSALAMUALAIKUM,

GIVEN VALUES:- M = 1000gm or 1kg ;
g = 10m/s^ ; t = 10s ; V =?


SOLUTION:- V = u+at

V = 0+ 10*10
V =100m/s

K.E. = 1/2MV^

= 1/2*1*100*100

= 5000 joule.

INSHAALLAH it will help you!
