Question

A toy of mass 0.1 kg acquires a speed of 5.0 m/s when pushed forward. What is the impulse given to the toy

Answer 1

here. initial velocity, u =0

and, time t = (v-u)/a

Ft = mat = ma x {(v-u)/a} = m(v-u) = 0.1 x 5 = 0. 5

Answer 2

0.5 Ns

Explanation:

F = m×a = 0.1×5 = 0.5 N

:- impulse = F × t = 0.5N × 1s = 0.5Ns
