Answer 1

Answer:

&

Explanation:

Given:- F=200N

t=3s

u=0m/s

(a) Impulse=Force × time

200N × 3s

Impulse=600Ns

(b) m=1200kg

F=ma

a= F

m

a= 200N

1200kg

a=0.16m/s²

a= v-u

t

v-u= at

v-u =0.16m/s² × 3s

v-u= 0.48m/s

[v-u is change in velocity]

therefore, change in velocity is 0.48m/s

Hope this will help you.
