Shown below is a waterslide constructed in the late 1800's. This slide was unique for its time due to the fact that a large number of small wheels along its length made friction negligible. Riders rode a small sled down the chute which ended with a horizontal section that caused the sled and rider to skim across the water much like a flat pebble. The chute was 9.76 m high at the top and 54.3 m long. Consider a rider and sled with a combined mass of 81.0 kg. They are pushed off the top of the slide from point A with a speed of 2.90 m/s, and they skim horizontally across the water a distance of 50 m before coming to rest. 9.76 m Engraving from Scientific American, July 1888 A (a) 20.0 m/ -54.3 m- 50.0 m (b) (a) Find the speed (in m/s) of the sled and rider at point C. 14.14 m/s (b) Model the force of water friction as a constant retarding force acting on a particle.

A spring with unstretched length of 14.3 cm has a spring constant of 4.63 N/m. The spring is lying on a horizontal surface, and is attached at one end to a vertical post. The spring can move freely around the post. The other end of the spring is attached to a puck of mass m. The puck is set into motion in a circle around the post with a period of 1.32 s. Assume the surface is frictionless, and the spring can be described by Hooke's law. (a) What is the extension of the spring as a function of m? (Assume x is in meters and m is in kilograms.
