Answer 1

Question:

A body of mass 5 kg starts from rest with an acceleration of 3ms-². The change in momentum in 10s is​

Answer:

Momentum= 150kg.m/s

Explanation:

Mass of the body (m)=5kg

Acceleration (a)= 3m/s^2

Initial velocity (u)= 0m/s (at rest)

Momentum of the body after time t=10s(p) = ?

Use,

Final velocity (v)= u + at

Final velocity (v) =0+3×10

Final velocity (v)= 0+30

Final velocity (v)=30m/s.

Then use,

Momentum(p)= Mass(m) × Velocity(v)

Momentum(p)= 5kg × 30m/s

Momentum(p)=150kg.m/s
