coefficient of kinetic friction

R13–5. The ball has a mass of 30 kg and a speed v = 4 m>s at the instant it is at its lowest point, u = 0°. Determine the tension in the cord and the rate at which the ball’s speed is decreasing at the instant u = 20°. Neglect the size of the ball.

R13–7. The 10-lb suitcase slides down the curved ramp for which the coefficient of kinetic friction is mk = 0.2. If at the instant it reaches point A it has a speed of 5 ft> s, determine the normal force on the suitcase and the rate of increase of its speed.
