Chapter 1, Problem 29P
. The roller coaster in Figure 1.39 starts at the top of a straight track that is inclined 30° with the horizontal. This causes it to accelerate at a rate of 4.9 m/s2 (1/2 g).
(a) What is the roller coasters speed after 3 s?
(b) How far does it travel during that time?

Model his body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test he finds that when hanging at rest from a 5.00 m length of the cord, his body weight stretches it by 1.55 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the bridge.
