At the end of the first section of the motion, riders are moving at what approximate speed?

A. \(3 \mathrm{~m} / \mathrm{s}\)

B. \(6 \mathrm{~m} / \mathrm{s}\)

C. \(9 \mathrm{~m} / \mathrm{s}\)

D. \(12 \mathrm{~m} / \mathrm{s}\)

A rider on a water slide goes through three different kinds of motion, as illustrated in Figure P3.78. Use the data and details from the figure to answer the above question.

Transcribed Image Text:

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. r-1.5 m 0=45% 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. FIGURE P3.78
