Answer the question number 2.
In the figure, the 200-lb crate is being pulled up the slope by the motor M. If the velocity of the point P is 2s³ ft/s (where s is the displacement of the crate), and the coefficient of kinetic friction between the crate and the slope is u = 0.2, what will the towing force applied by M be when the box has moved 10 ft up the slope?
A skier is travelling horizontally across frictionless snow at 10 m/s. He goes up an also frictionless slope and his speed drops to 5 m/s at the top when he resumed moving horizontally. How high did he go?
A person on an icy expedition is trying to lower a crate of mass m1 = 5.65 kg crate to the bottom of a steep ravine of height h2 21.8 m using a rope over a simple pulley. The person, who m2 frictionless %| weighs m2 = 60.9 kg, is being careful to lower the crate at a constant speed of 1.50 m/s. Unfortunately, when the crate reaches a point h = 12.1 meters above the ground, the person slips and the crate immediately accelerates toward the ground, dragging the hapless person across the ice and toward the edge of the cliff. h If we assume the ice is perfectly slick (that is, no friction between the person and the ice once he slips and falls down), at what speed will the crate hit the ground? Assume also that the rope is long enough to allow the crate to hit the ground before the crewman slides over the side of the cliff. speed: m/s At what speed will the person hit the bottom of the ravine? (Assume no air friction.) speed: m/s

(2) Four dollies (A, B, C and D) on a plane are connected by three ropes, ropes 1, 2 and 3, as shown in the diagram. The rightmost dolly is powered and pulled in the overall rightward direction by a force of magnitude F. The 4 dollies accelerate with the same acceleration. The friction between the ground and the dolly is negligible. At this point, answer the following questions. The rope does not stretch and the mass of the rope is neglected.< 台車D m4 ロープ3 m3 台車C ロープ2 m2 台車B ロープ1 m1 台車A F At this point, increase the strength of the F. Which rope breaks first.
