Your group of 3 to 4 students will submit a written response to this question on paper. You must still hand in all your
work for this problem. Ensure all group members' names are on the paper! In warehouses, boxes get lifted up and down a lot, which is usually done by a forklift. A forklift has a maximum load it can handle
so you need to know the force acting on the fork. As an example assume that you want to lift a heavy box with a forklift. The box
has a mass of 250kg . Use g = 9.8 ms‘sr2 a} What is the force (in newtons} that the forklift exerts on the box while the box is moving up at constant speed? Draw a free-body diagram with your answer. b) The forklift has just picked up the box off the ground. What is the force that the forklift exerts on box while the box moves up
and speeds up with an upward acceleration of 0.9 mfsz? Again, include a free-body diagram with your answer. Submit v

A 75 kg person is being pulled away from a burning building as shown in the figure
below. Calculate the tension (in N) in the two ropes (71 and 72) if the person is
motionless for some short time. Include a free-body diagram in your solution.
(Remember that tension is a force that is transmitted through the rope, and has the
same magnitude on both ends, always directed along the rope.)

Dog-sled
4 points possible (ungraded) A team of eight dogs pulls a sled with waxed wood runners on wet snow (mush!). The
dogs have average masses of 21 kg, and the loaded sled with its rider has a mass of
214 kg. {a} Calculate the magnitude of the acceleration starting from rest if each dog
exerts an average force of 185 N backward on the snow. {coefficients of friction for
the sled are gs: 0.14,yk= 0.1 } (b) What is the magnitude of the acceleration (in mfsz } once the sled starts to move? (c) For both situations, calculate the magnitude of the tension force (in N) between the
dogs and the sled Starting from rest: While the sled is moving:
