A0.25 kg ball is dropped from a 30 meter building. at the same time, a 2 kg ball is thrown downward with a 50 n force. neglecting air resistance and after it is thrown, the ball will have an acceleration (a) equal to 8 times that of the dropped ball. (b) equal to 1/8 of that of the dropped ball. (c) equal to that of the dropped ball. (d) always larger than, but not always 8 times larger than, that of the dropped ball. (e) always smaller than, but not always 8 times smaller than, that of the dropped ball.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
