Gayle runs at a speed of 4.00 m/s and dives on a sled, initially atrest on the top of a frictionless, snow-covered hill. aftershe has descended a vertical distance of 5.00m, her brother, who isinitially at rest, hops on her back, and they continue down thehill together.
gayle's mass is 50.0kg, the sled's mass is 5.00kg and her brotherhas a mass of 30.0kg.
what is their speed at the bottom of the hill if the total verticaldrop is 15.0m?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
