force = mass × acceleration
= 12 kg × 2 m/sec^2
= 24 newton
= 12 kg × 2 m/sec^2
= 24 newton
Riya09:
lets take the velocity of the body at 1 sec before it came to rest, as initial velocity
which is 2m/s
the time taken for the change of velocity is 1 sec
so acceleration = (0 - 2) ÷ 1 m/sec^2 = 2 m/sec^2
hope you get clear
thank you so much
your welcome
if you didn't get clear, let me know where you didn't understand. then i will try my best to make you understand
you are welcome and thanks for giving brainy answer
