Problem 3: An object of 5.0-kg mass is sliding down a slanted surface as shown (angle: 60 ° Length: 3.0 m). The initial speed of the object is 2.0 m/s. By the time the object reaches the end of the inclined surface its speed has increased to 2.5 m/s. Calculate a) The increase in the kinetic energy of the object b) The work done by the gravitational force. c) The work done by friction. d) The frictional force.
