You are playing basketball with some friends at the park when Nate Robinson, the 180 Ib(f) former New York Knicks point guard and only three-time winner of the NBA Slam Dunk Contest, stops by. You are curious about the forces the members of the hoop apparatus experience during a dunk. If Nate dunks and hangs on the rim of the hoop, find the forces supported by each member of the apparatus and the support reactions at D. Member IJ is a hand crank which can be used to adjust the height of the rim, and it acts as a two-force member. Post ABCD weighs 400 N and has a center of mass at noint C The assembly FEGH weighs

A speedboat with a mass of 529 kg (including the driver) is tethered to a fixed buoy by a strong 28.3 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m)×v2, where v denotes the boat's speed. Ignore any drag force on the cable. What is the force of the engine?
. The small piston of a hydraulic lift (g. 1) has a cross-sectional area of 3.00cm2, and its large piston has a cross-sectional area of 200cm2. What downward force of magnitude F1 must be applied to the small piston for the lift to raise a load whose weight is Fg = 15.0kN?
Ancient pyramid builders are balancinga uniform rectangular stoneslab of weight w, tipped at anangle u above the horizontal, usinga rope (Fig.). The rope isheld by five workers who share theforce equally. (a) If u = 20.0°, whatforce does each worker exert on therope? (b) As u increases, does eachworker have to exert more or lessforce than in part (a), assuming theydo not change the angle of the rope? Why? (c) At what angle do theworkers need to exert no force to balance the slab? What happens if uexceeds this value?

In order to burgle a local McDonald's, the Hamburglar must climb onto the roof. To do this, a ladder of length 3.31 m and mass 21.2 kg is placed leaning against a vertical wall, as shown in the image below. There is negligible friction between the ladder and the wall, but the same is not true for the ladder and the ground: us ≠ 0 between those two surfaces. Even with that friction, the ladder will start slipping if the angle ø ladder makes relative to the ground is less than 71.0°. Assuming the ladder is uniform (so that its center of gravity is located at its geometric center), what must be the maximum static frictional force (in N) that exists between the bottom of the ladder and the ground? Explain how you solved the problem involving a ladder leaning against a wall. Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!
A ball of mass mand radius Rrests at the edge of a step barrier of height has shown in thefigure. There is a horizontal force Tapplied to the ball from its top through a string wrapped around the ball to lift it above the barrier as shown in the figure. What is the minimum tension required to begin to lift the ball off the ground? (g = 9.8 m/s2, m = 1 kg, R = 0.5 m, h = 0.2 m).
