Matthew starts from rest on top of 8.45 m high sledding hill. he slides down the 32-degree incline and across the plateau at its base. the coefficient of friction between the sled and snow is 0.128 for the plateau and the hill is frictionless. matthew and the sled have a combined mass of 27.5 kg. determine the distance which matthew will slide along the level surface of the plateau before coming to a complete stop.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
