Question

A 15.0 kg sled is pushed with an initial speed of 5 m s on ice where the coefficient of kinetic friction is 0.050.

(a) How far will the sled travel before coming to rest?

(b) If the sled was instead pushed at 5 m s up an icy slope that has an incline angle of 10◦ , how far up the slope would the sled travel before stopping?

Answer #1

A girl on a sled coasts down a hill. Her speed is 6.0 m/s when
she reaches level ground at the bottom. The coefficient of kinetic
friction between the sled's runners and the hard, icy snow is
0.052, and the girl and sled together weigh 688 N. How far does the
sled travel on the level ground before coming to rest?

A sled is traveling at 15.0 m/s. It slides to rest under the
influence of friction in 2.54 s. What is the coefficient of kinetic
friction required to do this?

A 150 gram block is pushed up a ramp set at a 20 degree angle
with respect to the horizontal. Its initial speed is 1.24 m/s as a
result of the push, and it travels 14.0 cm up the incline before
coming to rest. How far would it travel down the ramp before coming
to rest if the push was in the opposite direction but the initial
speed was the same?

The initial speed of a 2.58-kg box traveling up a plane inclined
37° to the horizontal is 4.55 m/s. The coefficient of kinetic
friction between the box and the plane is 0.30.
(a) How far along the incline does the box travel before coming to
a stop?
---m
(b) What is its speed when it has traveled half the distance found
in Part (a)?
---m/s

A block is given an initial push at the bottom of a 22 degree
inclined plane. If the coefficient of kinetic friction between the
block and plane is 0.32, and the initial speed of the block at the
bottom of the incline is 4.00 m/s, how far up the incline does the
block travel before coming to rest?

A mass m = 13 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.07, for a
distance d = 5.1 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 33° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 33°
(thus on the incline it is...

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.

In a circus performance, a monkey is strapped to a sled and both
are given an initial speed of 2.0 m/s up a 18.0° inclined track.
The combined mass of monkey and sled is 22 kg, and the coefficient
of kinetic friction between sled and incline is 0.20. How far up
the incline do the monkey and sled move? (m)
ANSWER IS NOT .40 m

A 53.6-kg person, running horizontally with a velocity of +4.72
m/s, jumps onto a 19.1-kg sled that is initially at rest.
(a) Ignoring the effects of friction during the
collision, find the velocity of the sled and person as they move
away. (b)The sled and person coast 30.0 m on level
snow before coming to rest. What is the coefficient of kinetic
friction between the sled and the snow?

In a circus performance, a monkey is strapped to a sled and both
are given an initial speed of 3.0 m/s up a 25.0° inclined track.
The combined mass of monkey and sled is 16 kg, and the coefficient
of kinetic friction between sled and incline is 0.20. How far up
the incline do the monkey and sled move?
_______m
