1. A compact car, mass of 725 kg, is moving at 100m/s.
a. Find its momentum.

b. At what velocity is the momentum of a larger car (than the one above) with a mass of 2175 kg, equal to that of the smaller car?

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s.a. determine jay’s mass.b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.
