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?

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 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. Use the work-energy theorem to find the total work...

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 speed of 92 km/h. If slipping just begins at this speed, what is the coefficient of static friction between the...

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 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...
