Answer #1

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

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.
a) What is the height of the slide?
b) What is the change in gravitational potential energy of the
child?
c) Draw the free-body diagram of the child
d) Calculate the frictional force on the child
e) How much energy...

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 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.)

A child slides down a snow‑covered slope on a sled. At the top
of the slope, her mother gives her a push to start her off with a
speed of 0.85 m/s. The frictional force acting on the sled is
one‑fifth of the combined weight of the child and the sled. If she
travels for a distance of 23.5 m and her speed at the bottom is
3.75 m/s, calculate the angle that the slope makes with the
horizontal.

A child leaves her book bag on a slide. The bag, which is at the
top of the slide, starts from rest and reaches the bottom in 1.75
s. The mass of the book bag is 3.20 kg, the length of the slide is
3.30 m and the angle of incline is 28.0°. (Assume the +x-axis to be
parallel to and down the slide. For all values, enter the magnitude
only.)
(a) With what acceleration does the bag go down...

Moving at an initial speed of vi = 2.00 m/s, Jimmy slides from a
height of h = 5.00 m down a straight playground slide, which is
inclined at θ = 55° above the horizontal. At the bottom of the
slide, Jimmy is moving at vf = 9.00 m/s. By determining the change
in mechanical energy, calculate the coefficient of kinetic friction
between Jimmy and the slide.

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.
