The first object weighted 10,000 kg, and the second object had a mass of 13,000 kg. If the objects were 1 meter apart, use Newton's Law of Universal Gravitation to determine the force of attraction between the two objects.

A0.17kg ball rolls at 0.75m/s to the right on a frictionless surface and collides with a 0.17kg ball rolling to the left at 0.65m/s. (elastic collision) what is the final velocity of the second ball when the first is 0.5m/s to the left? what is the change in kinetic energy before and after?

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

When a bicycle coasts uphill, it moves slower and slower as it climbs. why? a. its kinetic energy is transforming into heat energy. b. its potential energy is transforming into kinetic energy. c. its kinetic energy is transforming into potential energy and heat energy. d. its potential energy is transforming into kinetic energy and heat energy.
