Question

a) Shrek finds donkey in a cart (total mass 50 kg) on the side of the road. He starts to pull the cart along a smooth road with a coefficient of friction 0.2 with a force of 120 N [FWD]. If he accelerated to a speed of 15 km/h, how far did the cart move during acceleration?

b) This is a multiple motion question. Shrek maintains a constant speed after his initial acceleration, then breaks into a sprint. He at this point is pulling on the cart with a force of 125 N (FWD 20 UP) and maintains this for 10s. How fast is he going at this point?

Shrek finds donkey in a cart (total mass 50 kg) on the side of
the road. He starts to pull the cart along a smooth road with a
coefficient of friction 0.2 with a force of 120 N [FWD]. If he
accelerated to a speed of 15 km/h, how far did the cart move during
acceleration?
Continued from Question 1 - so hey guess what? This is a
multiple motion question. Shrek maintains a constant speed after
his initial acceleration,...

A cart for hauling ore out of a gold mine has a mass of 411 kg,
including its load. The cart runs along a straight stretch of track
that climbs a shallow 4.45∘ incline. A donkey, which is trudging
along and to the side of the track, has the unenviable job of
pulling the cart up the slope with a 393 N force for a distance of
127 m by means of a rope that is parallel to the slope...

A cart with a mass of 2.0 kg is given quick push up a ramp so
that it starts with a speed of 3.0 m/s. Angle of the ramp is 30
degrees.
Friction can be ignored.
• What’s value of the forces that act on the cart? •
What is the net force and acceleration of the cart? •
What distance along the ramp does the cart travel before coming
to a stop?
Also if possible include Free

A sled with mass 15 kg moves in a straight line on a horizontal
surface as it is being pulled by a force F at an angle of 30°with
the direction of motion. A force of friction of 10 N acts on the
sled. At one point in its path, its speed is 4.0 m/s; after it has
traveled a distance 5.0 m beyond this point, its speed is 7.0
m/s.

3-A 1.0 kg block slides down an inclined plane of 39
0 from the horizontal. If the
block starts from rest and hits the bottom in 5.1 s,
what is the speed of the block, in the unit m/s, at the bottom of
the incline? Assume a frictionless plane.
4-A bus negotiates a turn of radius 103 m while traveling at a

A curve of radius 20 m is banked so that a 1000 kg car traveling
at 60 km/h can round it even if the road is so icy that the
coefficient of static friction is approximately zero. The
acceleration of gravity is 9.81 m/s 2 . ? Find the minimum speed at
which a car can travel around this curve without skidding if the
coefficient of static friction between the road and the tires is
0.2. Answer in units of...

A chain of metal links with total mass m = 6 kg is coiled up in
a tight ball on a low-friction table. You pull on a link at one end
of the chain with a constant force F = 69 N. Eventually the chain
straightens out to its full length L = 1.1 m, and you keep pulling
until you have pulled your end of the chain a total distance d =
3.9 m (diagram is not to scale)....

a- What is the maximum speed with which a 1200-kg car can round
a turn of radius 90.0 m on a flat road if the coefficient of static
friction between tires and road is 0.60?
Part b
If the jet is moving at a speed of 1140 km/h at the lowest point
of the loop, determine the minimum radius of the circle so that the
centripetal acceleration at the lowest point does not exceed 6.0
g's.

A large tractor-trailer of total mass M = 10 metric tons
(10,000 kg) is traveling down I-70 in Colorado, coming down from
the Rocky Mountains into Denver. A segment of this road that is 25
kilometers long descends a total of 1000 meters. Suppose that the
truck driver wants to drive at a constant speed of v = 50
km/hr.
(a) What is the work done on the truck by its brakes during this
motion? (Give both the sign and...
