Question

the velocity of a particle of mass 150g change from 8m/s to 12m/s in two second. assuming a constant force is acting on it. find it magnitude force​

Answer 1

Explanation:

m=150g=0.15kg

F=ma

a=(v-u)/t

a=(12-8)/2=4/2=2metre/second2

We know F=ma=0.15×2

Therefore

F=0.3N

Answer 2

Answer:

a=(v2-v1)/t = 4/2 = 2

Force F= ma

=150×10^-3×2

=300×10^-3

=0.3N
