A 180-lb snowboarder has speed v = 15 ft /sec whenin the position shown on the halfpipe
Chapter 3, Problem 3/58(choose chapter or problem)
A 180 -lb snowboarder has speed \(v=15 \mathrm{ft} / \mathrm{sec}\) 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 \(\mu_k=0.10\) 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 3 feet from the surface of the snow.
