Question

If force acting on a body is 10n . Find acceleration if mass of the body is 2 kg

Answer 1

Answer:

as we know

F= ma

10=2a

a =5

Answer 2

here is your answer

Force = mass× acceleration

F =10 N

= 2 kg

a = F/m = 10/2 = 5 m/s²

i)now, u = 0

t = 3 sec

v = u + at = 0 + 3×5 = 15 m/s

ii) initial momentum = mu = 2×0 =0

final momentum = mv = 2×15 = 30 kg m/s

change in momentum = final momentum - initial momentum

= 30 -0 = 30 kg m/s
