Momentum practice problems
use your knowledge about solving equations to work out the following problems. be
sure to show all your work with units:
1. if the truck has a mass of 2,000 kilograms, what is its momentum? (v = 35 m/s)
express your answer in kg: m/sec.
2. if the car has a mass of 1,000 kilograms, what is its momentum? (v = 35 m/s)
3. an 8-kilogram bowling ball is rolling in a straight line toward you. if its momentum is 16
kg. m/sec, how fast is it traveling?
4. a beach ball is rolling in a straight line toward you at a speed of 0.5 m/sec. its
momentum is 0.25 kg. m/sec. what is the mass of the beach ball?
5. a 4.000-kilogram truck travels in a straight line at 10.0 m/sec. what is its momentum?
6. a 1,400-kilogram car is also traveling in a straight line. its momentum is equal to that
of the truck in the previous question. what is the velocity of the car?
