A 12 N object is attached vertically by a string to a frictionless car that runs along a level track. The car with mass m kg covers a distance of 1.25 m in 5.0 s after it starts from the rest. Grind the (a) final speed of the car, (b) loss in potential energy of the 12 N object in falling through a distance of 1.25 m, (c) again in kinetic energy of the car and the hanging object, and (d) mass of the car.
