Question

1. A 1-kilogram turtle crawls in a straight line at a speed of 0.01m/sec. What is
the turtle's momentum?
2. Which would take more force to stop in 10 seconds: an 8.0-kilogram ball rolling in a straight line at a speed of 0.2m/sec or a 4.0-kilogram ball rolling along the same path at a speed of 1.0m/sec?
3. The momentum of a car traveling in a straight line at 20m/sec is
24,500kg-m/sec. What is the car's mass?
4. Another pitcher throws the same baseball (mass=0.05 kg) in a straight line.
Its momentum is 2.1kg.m/sec. What is the velocity of the ball?​
