Sample Past AP Physics B Energy problems Topic: Friction and forces, work and energy 10 kg 1981BI. A 10-kilogram block is pushed along a rough horizontal surface by a constant horizontal force F as shown above. At time t = 0, the velocity v of the block is 6.0 meters per second in the same direction as the force. The coefficient of sliding friction is 0.2. Assume g = 10 meters per second squared. a. Calculate the force F necessary to keep the velocity constant. The force is now changed to a Larger constant value F'. The block accelerates so that its kinetic energy increases by 60 joules while it slides a distance of 4.0 meters. b. Calculate the force F'. c. Calculate the acceleration of the block
