When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 994 N and the drag force has a magnitude of 1063 N. The mass of the sky diver is 101 kg. Take
upward to be the positive direction. What is his acceleration, including sign?

A box is placed in the bed of a pick-up truck or similar flat-bed vehicle. What the maximum acceleration the truck can undergo for which the block does not slide on the flat vehicle bed? The coefficient of static friction is mu, the vehicle mass is massvehicle, and the box mass is mbox. Derive an expression for max vehicle acceleration in terms of mu, gravitational acceleration, mvehicle, and mbox. Note that your derived expression may not contain all of these terms.
A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 140.0 N at an angle of 17.0° above the horizontal. The box has a mass of 25.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (a) Find the acceleration of the box. m/s² up the incline (b) The student now starts moving the box up a 10.0° incline, keeping her 140.0 N force directed at 17.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box? m/s² up the incline
When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 965 N and the drag force has a magnitude of 1016 N. The mass of the sky diver is 98.5 kg. Take upward to be the positive direction. What is his acceleration, including sign?
A 75 kg skier was pushed up a slope of 21.0 degrees west with an inititial velocity of 4.0 m/s. After the inital push, it is not pushed further with the up-slope force. The kinetic coefficient of friction between the skis and the snow is 0.14 and the static coefficient is 0.19. a) What is the acceleration (deceleration) of the skier after the push? b) If his initial velocity was 4.0 m/s, how far up the slope will he move before he stops?

An elevator loaded with tourists has a mass of 1750 kg. a.) The elevator accelerates upward (in the positive direction) from rest at a rate of 1.55 m/s2 for 2.3 s. Calculate the tension in the cable supporting the elevator in newtons b.) The elevator continues upward at constant velocity for 8.5 s. What is the tension in the cable, in Newtons, during this time? The elevator experiences a negative acceleration at a rate of 0.65 m/s2 for 2.6 s. What is the tension in the cable, in Newtons, during this period of negative accleration? c.) How far, in meters, has the elevator moved above its original starting point?
A mass of 3.2 kg is initially at rest upon a horizontal surface. An applied force of 42 N i then acts on the mass. If the coefficient of kinetic friction regarding the system is 0.868, what is the magnitude of the object's acceleration? Assume that all quantities are good to 3 significant figures, All numeric answers should be entered rounded to 3 significant figure.
