Question

The momentum of a 1000-Kg vehicle moving North at a velocity of 25 m/s is _________________. (Remember p = mv.) *

Answer 1

Answer:

Initial velocity (u) = 20m/s

Final velocity (v) = 0m/s

Distance moved (s) = 50m

We know,

Now,

Hence, the unbalanced force acting on the vehicle is -4000N.

Answer 2

Answer:

500 kg m/s

Given :    m=1000 kg                   v=0.5 m/s

∴  Momentum of the car         P=mv=1000×0.5=500  kg m/s
