Question

The velocity of an object of mass m increases from u to v.
State, in terms of m, u and v, the change of momentum of the object.

Answer 1

Answer:

m (v - u)

Explanation:

Momentum = Mass× Velocity

Initial momentum = Mass× Initial Velocity

P1 = m × u

Final momentum = mass × Final Velocity

P2 = m × v

Change in momentum = Final momentum - Initial momentum

P2-P1 = mv - mu

= m( v-u )
