Answer:
Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of myosin to actin filaments, allowing myosin to function as a motor that drives filament sliding.
He needs to improve his endurance time.

For no friction, Θ = arctan[v²/(R*g)] = 32.68°
Anet = √[(v²/R + g²] = 33.2 ft/sec²
Af = Anet*sinΘ = 17.93 ft/sec²
Ff = m*Af = (3200/32.2)*Af = 1781.9 lb along the slope.
