Question

Starting from rest at the top, a child slides down the water slide at a swimming pool and enters the water at a final speed of 5.95 m/s. At what final speed would the child enter the water if the water slide were twice as high? Ignore friction and resistance from the air and the water lubricating the slide.

Answer #1

A water slide is constructed so that swimmers, starting from
rest at the top of the slide, leave the end of the slide traveling
horizontally. As the drawing shows, one person hits the water 5.00
m from the end of the slide in a time of 0.598 s after leaving the
slide. Ignore friction and air resistance, find the height H.

A student of mass 65.4 kg, starting at rest, slides down a slide
18.2 m long, tilted at an angle of 32.1° with respect to the
horizontal. If the coefficient of kinetic friction between the
student and the slide is 0.133, find the force of kinetic friction,
the acceleration, and the speed she is traveling when she reaches
the bottom of the slide. (Enter the magnitudes.)

At the Monterey sports center pool there is a water slide whose
top is 5.00 meters above the pool. The total length of
the slide is 15.0 meters because it ‘winds’ its way down to the
water. Since water is running down the slide, there is very little
friction (we will assume none) between the swimmers’ bathing suits
and the slide surface.

A child whose weight is 325 N slides down a 9.2 m playground
slide that makes an angle of 30° with the horizontal. The
coefficient of kinetic friction between slide and child is 0.20. If
she starts at the top with a speed of 0.55 m/s, what is her speed
at the bottom?

A 52.4 kg child slides down a water slide with a velocity of 1.1
m/sec at the top. At the bottom of the slide, she is moving
horizontally, y=1.5 meters above the water. She splashes into the
water d=2 meters to the left of the bottom of the slide.1) Assuming
potential energy to be zero at the water level, what is the
mechanical energy of the child at the top of the slide? MEo=?. 2)

A child whose weight is 325 N slides down a 9.2 m
playground slide that makes an angle of 30° with the horizontal.
The coefficient of kinetic friction between slide and child is
0.20. If she starts at the top with a speed of 0.55 m/s, what is
her speed at the bottom?
A.11 m/s
B.33 m/s
C.22 m/s
D.9 m/s

A child whose weight is 242 N slides down a 7.40 m playground
slide that makes an angle of 41.0° with the horizontal. The
coefficient of kinetic friction between slide and child is 0.0950.
(a) How much energy is transferred to thermal energy? (b) If she
starts at the top with a speed of 0.440 m/s, what is her speed at
the bottom?

A child whose weight is 281 N slides down a 6.10 m playground
slide that makes an angle of 47.0° with the horizontal. The
coefficient of kinetic friction between slide and child is 0.160.

energy? (b) If she starts at the top with a speed
of 0.311 m/s, what is her speed at the bottom?

A 35 kg child slides down a playground slide at a constant
speed. The slide has a height of 3.8 m and is 7.6 m long. Using the
law of conservation of energy, find the magnitude of the kinetic
friction force acting on the child.

A child whose weight is 190N slides down a playground slide that
makes an angle of 29 degrees with a horizontal and has a length of
9.4m. The coefficient of kinetic friction between the slide and the
child is 0.35.

d) Calculate the frictional force on the child
e) How much energy...
