Question

(a)define si unit of force . (a)a force of 2n is acting the body changes its velocity uniformly from 2m/s to 5m/s in 10sec. Calculate the mass of body.

Answer 1

S,.I. unit of force s newton.
1 newton is the force produced on any body with a mass of 1 kg moving with an acceleration of 1 m/s2.
Given,
F = ma
2 = m* 5-2/10
2 = m* 0.3
m = 6.6 kg.
