Arider on a water slide goes through three different kinds of motion, as illustrated in the figure below. use the data and the details from the figure to answer the following questions. remember, when an object is in a circular motion it is accelerated toward the center of the circle with acceleration a = v2/r
a) at the end of the first section of the motion, riders are moving at approximately what speed? show your work for partial credit.
a. 3 m/s b. 6 m/s c. 9 m/s d. 12 m/s
b) suppose the acceleration during the second section of the motion is too large to be comfortable for the 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 f the ramp.
c) what is the vertical component of the velocity of the rider as he hits the water? show your work for partial credit.
a. 2.4 m/s b. 3.4 m/s c. 5.2 m/s d. 9.1 m/s
d) suppose the designers of the water slide want to adjust the height h above the water so that the riders land twice as far away from the bottom of the slide. what would be the necessary height above the water? show your work for partial credit.
a. 1.2 m b. 1.8 m c. 2.4 m d. 3.0 m
e) during which section of the motion is the magnitude of the acceleration experienced by the rider the greatest?
a. the first b. the second c. the third d. it is the same in all sections
