a) A child slides down a water slide at an amusement park froman initial height h. The slide can be consideredfrictionless because of the water flowing down it. Can the equationfor conservation of mechanical energy be used on the child?
YesNo    Â
(b) Is the mass of the child a factor in determining his speed atthe bottom of the slide?
YesNo    Â
(c) The child drops straight down rather than following the curvedramp of the slide. In which case will he be traveling faster atground level?
following the curved rampdropping straightdown     same speed in either case
(d) If friction is present, how would the conservation-of-energyequation be modified?
(e) Find the maximum speed of the child when the slide isfrictionless if the initial height of the slide is 13.5 m. (Assumethe child is initially at rest.)
m/s
