A stone of mass 0.5kg is throw upward with a velocity of 40m/s. Calculate the Kinetic energy of the stone if the stone descends to a hight of 30m. Find the potential energy at this hight (g=10m/s)

Aferris wheel is a vertical, circular amusement ride with radius 9 m. riders sit on seats that swivel to remain horizontal. the ferris wheel rotates at a constant rate, going around once in 9 s. consider a rider whose mass is 56 kg. at the bottom of the ride, what is the perpendicular component of the rate of change of the rider's momentum? at the bottom of the ride, what is the vector force exerted by the seat on the rider?
