A cyclist approaches the bottom of a gradual hill at a speed of 11 m/s. The hill is 5.0 m high, and the cyclist estimates that she is going fast enough to coast up over it without pedaling. Ignoring air resistance and friction.
(a) find thd speed at which the cyclist crest the hill.
(b) A second cyclist repeats the same route, but his weight plus the bike is douh velocity as he crests the hill?
(c) A third cyclist of total mass 70kg repeats the same route. He uses a cheap bike, What is the resultant velocity as he crests the hill?
