The lecture Momentum: Example by Jared Rovny is from the course Momentum.
The momentum of a car traveling in a straight line at 20 m/sec is 24,500 kg.m/sec. What is the car’s mass?
An 8kilogram bowling ball is rolling in a straight line toward you. If its momentum is 16 kg.m/sec, how fast is it traveling?
A pitcher throws a baseball in a straight line. If its momentum is 2.1 kg.m/sec. and the mass is 0.14 kg, what is the velocity of the ball?
A 72 kg boy and a 48 kg girl, both wearing ice skates, face each other at rest on a skating rink. The boy pushes the girl, sending her eastward with a speed of 6.8 m/s. When the impulse is completed, the boy and girl are a distance of 1.4 meters apart. Determine the distance of separation between the boy and the girl 5.0 seconds after the impulse is completed.
