A 173-lb snowboarder has speed v = 15 ft/sec when in the position shown on the halfpipe. Determine the normal force on his
snowboard and the magnitude of his total acceleration at the instant depicted. Use a value HK = 0.06 for the coefficient of kinetic
friction between the snowboard and the surface. Neglect the weight of the snowboard and assume that the mass center G of the
snowboarder is 2.2 feet from the surface of the snow.

The system is released from rest with the spring initially stretched 2 in. Calculate the velocity of the 100-lb cylinder after it has dropped 6 in. Also determine the maximum drop distance of the cylinder. Neglect the mass and friction of the pulleys 100 lb
A constant force of F acts on a mass as shown. The mass starts its motion from rest at position 1, the unstretched lenght of the spring is 250 mm, and the spring modulus is k = 1.5 kN/m. Neglecting the friction, determine the required force F to cause the 2 - kg mass to have a speed of v2 = 1.5 m/s at position 2.
