(a) A child slides down a water slide at an amusement park from aninitial height h. The slide can be considered frictionless becauseof the water flowing down it. Can the equation for conservation ofmechanical energy be used on the child?

1
yes
no



(b) Is the mass of the child a factor in determining his speed atthe bottom of the slide?

2
yes
no



(c) The child drops straight down rather than following the curvedramp of the slide. In which case will he be traveling faster atground level?

3
following the curved ramp
dropping straight down
same speed in either case
