b) How fast is the bus sliding after 5.00 s?

Answer #1

A 7kg box starts at the top of a 10m hill and slides
without friction down the hill. How fast will it be going at the
bottom of the hill?

A 5.0 kg box slides down a 5.0 m high frictionless hill,
starting from rest, across a 2.0 m wide horizontal surface, then
hits a horizontal spring with spring constant 500 N/m. The ground
under the spring is frictionless, but the 2.0 m wide horizontal
surface is rough with a coefficient of kinetic friction of
0.25.
a. What is the speed of the box just before reaching the rough
surface?
b. What is the speed of the box just before...

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 car with snow tyres (m=1500 kg) is sliding down an icy hill
with a slope of 15º at an initial speed of 8 m/s.) The coefficient
of kinetic friction is 0.4.
a. What is the stopping distance
b.After sliding 12 m what is the momentum of the car?
c. At this point of having travelled 12m the car collides into
another car (m=1000 kg) travelling 3 m/s in the same direction down
the slope and they are stuck together....

A 2.0 kg stone slides from rest down a hill 5.0 m high and is
observed to be moving at 6.0 m/s at the bottom. During this
process, how much thermal energy have been produced due to the
friction?

Starting from rest, a 4.30-kg block slides 1.80 m down a rough
30.0° incline. The coefficient of kinetic friction between the
block and the incline is ?k = 0.436.
(a) Determine the work done by the force of gravity. J
(b) Determine the work done by the friction force between block
and incline. J
(c) Determine the work done by the normal force. J
(d) Qualitatively, how would the answers change if a shorter
ramp at a steeper angle were...

A 1 kg block, starting from rest, slides down a 22 degree
inclined plane that is .55m tall. At the bottom, the 1 kg block
collides with a 3 kg block. The two blocks stick together and slide
.52 m on a friction less horizontal surface for .52 sec. What is
the speed of the 1kg block before it collides with the 3 kg block?
What is the acceleration of the 1kg block as it travels down the
inclined plane?...

starting at rest, a mass of 2.50 kg slides down an incline of
65.0 degrees. If the coefficient of kinetic friction is know to be
0.435, what is the speed of the mass after slinging 2.50 m down the
incline

A block slides down an inclined plane, starting from rest and
being pushed with a constant acceleration of 5.25 m/s2 over a
distance of 18.0 cm. It then decelerates at a constant rate of 1.10
m/s2 (because of friction), until it again comes to rest. Find the
total time the block is in motion.

A 70.0kg skiier slides down a hill from a height of 125m. His
initial speed is 5m/s.
a) If there is no friction or air resistance, what is his speed
when he is at a height of 80.0m? ??????????????
b) If the coefficient of friction between him and the snow is
0.100, and the hill has an angle of elevation of 3??0°,
what is his speed when he reaches 80.0m?(neglect air resistance
still) ????????????
c) Now (at a height of...
