Question

a compact car with mass= 1000 kg has a velocity with magnitude 25 m/s. what is the magnitude of its momentum

Answer 1

The momentum of an object is given by

`p=mv`
where
m is the object's mass
v is its velocity
For the car in this problem, m=1000 kg and v=25 m/s, therefore the momentum of the car is

`p=mv=(1000 kg)(25 m/s)=25000 kg m/s`
