Question

Quinn is at rest at the top of a playground slide. The main part of the slide is 5.0 m long, and it is tipped at a 30 degree angle. Quinn starts sliding, moving down the tipped section, and then the slide levels out so that he leaves the slide at 2.0 m/s, moving horizontally. Quinn's mass is 24kg.

A) If we consider the osolated system of earch+slide+Quinn, what is the amount of work done on such a system?

B) what is the work-energy equation for such a system?

C) what is the initial and final kinetic energy of the system?

D) what is the change in potential energy of the system?

E) How much thermal energy is deposited in his trousers and in the slide?

Answer #1

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 20 kg child slides down a 3.8-m-high playground slide. She
starts from rest, and her speed at the bottom is 2.6 m/s. What is
the change in thermal energy of the slide and the seat of her
pants? Express your answer with the appropriate units

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 4.08 kg box begins to slide from rest through a plane inclined
at 25.0 degrees (with respect to the horizontal) and which is 7.00
m long. The friction force between the box and the inclined plane
is 5.0 N. (explain each process and how you got to the answer)
Determine:
(a) the speed of the box when reaching the end of the inclined
plane (using what was learned in work / energy): Answer
(b) the coefficient of kinetic friction:...

A playground merry-go-round of radius ? = 2.0 m has a moment of
inertia ? = 250 kg ⋅ m^2 is rotating at 15 rpm about a
frictionless, vertical axle. Facing the axle, a 25-kg child hops
onto the merry-goround and manages to sit down on the edge. (a) (10
pts) What is the total angular momentum of the
‘merry-go-round-child’ system before and after the child hops on
the the merry-go-round? (b) (10 pts) What is the new angular speed,...

49) A 2.0-kg box is pushed from rest by a person exerting a
constant force of 50 N. The person exerts this force
over a distance of 3.0 m before releasing the box and letting it
slide to a stop. The coefficient of kinetic friction between the
box and the floor is 0.15. (a) Draw a motion diagram showing the
motion of the box from the moment the person begins pushing to the
moment the box stops moving. (b) Represent...

The hill is covered in gravel so that the truck's wheels will
slide up the hill instead of rolling up the hill. The coefficient
of kinetic friction between the tires and the gravel is
?k. This design has a spring at the top of the
ramp that will help to stop the trucks. This spring is located at
height h. The spring will compress until the truck stops,
and then a latch will keep the spring from decompressing
(stretching back...

Mazur 9.40: Two identical 0.50 kg carts, each 0.10 m long, are
at rest on a low-friction track and are connected by a spring that
is initially at its relaxed length of 0.50 m and is of negligible
inertia. You give the cart on the left a push to the right (that
is, toward the other cart), exerting a constant 5.0-N force. You
stop pushing at the instant when the cart has moved 0.40 m. At this
instant, the relative...
