Question

a car of mass 150 kg is moving with a speed of 20 ms-1 after 25 seconds, the velocity is increased by 10ms-1, then what is the change in momentum​

Answer 1

Answer:

-1500kg m/s

Explanation:

momentum formula

p=mv (p is momentum,m is mass,v is velocity)

change in momentum

Δp=m.Δv

Δp=m(vf-vi)

now put the values of m, VP and vi

Δp=150kg(10m/s-20m/s)

Δp=150kg *-10m/s

Δp=-1500kg m/s. answer
