A child slides down an icy hill on a tube. Once the child reaches the flat surface at the bottom of the hill, she is traveling at a speed of 15 m/s. If the coefficient of kinetic friction between the tube and the snow is 0.15 and the combined mass of the child-sled system is 40-kg, how far will the child slide before coming to rest?

True or false a high force means an object is moving fast100 points!

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
