Question

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.

slope angle with the horizontal: _____________________________

Answer #1

Calculate the final velocity of a child and sled at the bottom
of a hill covered in snow if the mass of the child is 65 kg, the
sled is 8 kg using energy calculations instead of the free-body
diagrams and force analysis. The length of the hill is 1000 m and
the slope is at 55 deg. angle. mus of k = 0.015.
Once at the bottom of the hill, how far must the sled travel in
order to...

A
33.5 lb child holding a 10.8 kg sled starts running towards a
downward slope. The child then jumps on the sled with an initial
speed of 0.640 m/s and then slides down the frictionless slope. The
child with sled has a speed of 5.25 m/s at the bottom of the hill.
a) What is the height of the hill?
b) What is the gravitational potential energy of the
child/sled at bottom of the hill?

A 60.0-kg skier coasts up a snow-covered hill that makes an
angle of 23.5 ° with the horizontal. The initial speed of the skier
is 9.17 m/s. After coasting a distance of 1.45 m up the slope, the
speed of the skier is 3.65 m/s. (a) Find the work
done by the kinetic frictional force that acts on the skis.
(b) What is the magnitude of the kinetic
frictional force?

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 15-kg sled is being pulled along the horizontal snow-covered
ground by a horizontal force of 27 N. Starting from rest, the sled
attains a speed of 2.1 m/s in 7.5 m.
Find the coefficient of kinetic friction between the runners of
the sled and the snow.

A doctor pushed a 16-kg sled along the horizontal snow-covered
ground by a horizontal force of 24 N. Starting from rest, the sled
attains a speed of 2.0 m/s in 8.0 m. Find the coefficient of
kinetic friction between the runners of the sled and the snow
I DON'T WANT THE SOLUTION. ONLY THE DIAGRAM.

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?

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 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?
