Question

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, 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?

Answer #1

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...

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.

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)....

It is generally a good idea to gain an understanding of the
"size" of units. Consider the objects and calculate the kinetic
energy of each one.
