Question

The velocity of a particle of mass 50 gram changes to 8 meter per
second to 12 meter per second into seconds assuming that a constant force act on it
find the magnitude of the force.​

Answer 1

Explanation:

force = mass × acceleration.

acceleration = change in velocity / time.

a = 12-8/ 2 = 2 m/s

m = 150 g = 0.15 kg.

since u have to convert all to S.I units or c.gs units.

i am doing it in s.i. units.

force = 0.15 × 2 kg m/s

force = 0.3 N..

Hope it helps you
