Question

A rider on a water slide goes through three different kinds of motion, as illustrated is shown. Use the data and details from the figure to answer the following question.

Suppose the acceleration during the second section of the motion is too large to be comfortable for riders. What change could be made to decrease the acceleration during this section?
A. Reduce the radius of the circular segment.
B. Increase the radius of the circular segment.
C. Increase the angle of the ramp.
D. Increase the length of the ramp.

L=6.0 m
1. The first section of the motion is a
ramp with no friction; riders start at
rest and accelerate down the ramp.
2. The second section of the
motion is a circular segment
that changes the direction of
motion; riders go around this
circular segment at a constant
speed and end with a velocity ..
that is horizontal.
0 = 45°/
/r= 1.5 m
h=0.60 m
3. The third section of the motion is a parabolic trajectory
through the air at the end of which riders land in the water.
