A1500 kg car traveling east at 40 km/hr turns a corner and speeds up to a velocity of 50 km/hr due north. what is the change in the car's momentum?

Change in momentum is

Solution:

The momentum of any body is the product of its mass and the velocity associated with the body and is generally given by:

Now, as per the question:

Mass of the car, M = 1500 kg

The velocity in the east direction,

The velocity in the north direction,

Now, the momentum of the car in the east direction:

Now, the momentum of the car in the north direction:

Change in momentum is given by:

Now,

(Since, )

answer: good job it's all correct !
