Review. A uniform board of length L is sliding along a smooth, frictionless, horizontal plane as shown in Figure P8.45a. The board then slides across the boundary with a rough horizontal surface. The coefficient of kinetic friction between the board and the second surface is μk. (a) Find the acceleration of the board at the moment its front end has traveled a distance x beyond the boundary. (b) The board stops at the moment its back end reaches the boundary as shown in Figure P8.45b. Find the initial speed v of the board.

- To give a pet hamster exercise, some people put the hamster in a ventilated ball andallow it roam around the house(Fig. P13.66). When a hamsteris in such a ball, it can cross atypical room in a few minutes.Estimate the total kinetic energyin the ball-hamster system.

If the puck is moving at an initial speed of 12.0 m/s, (a) what is the force of kinetic friction? (b) What is the acceleration of the puck? (c) How long does it take for the puck to come to rest? (d) What distance does the puck travel during that time? (e) What total work does friction do on the puck? (f) What average power does friction generate in the puck during that time?

Another performer rides on the bale of hay like a cowboy. After the arrow enters the bale, the balearrow system slides roughly 5 m along the ice. Estimate the initial speed of the arrow. Is there a trick to this stunt? FIGURE P11.24arrow_forward
- Pregnancy dramatically affects the energetics of swimming for female dolphins. Dolphins have an approximately circular cross section and are very streamlined. A typical dolphin has a girth—the circumference at the widest part of the body—of 1.4 m and a drag coefficient of 0.090. Advanced pregnancy increases the girth to 1.7 m and, with a less streamlined shape, the drag coefficient to 0.22. Dolphins typically cruise at a speed of 3.4 m/s a.What will be the cruising speed of a pregnant dolphin if she swims with the same power output as before becoming pregnant?arrow_forwardProblem 3. James Bond is pursued by evil henchmen across a ski resort. He ends up at the top of a high jump runway, whose slope is 36deg. With nowhere else to go and without his trusty Walther PPK, he has no option but to go for it. He pushes himself off to an initial speed of V0=2 m/s and slides down the runway. The kinetic friction coefficient between his waxed wood skis and the snow is 0.10. The level of the takeoff point of this runway is H=50m below the level of the launch point. At the takeoff point, the runway is horizontal. Below that point, the runway reverts to a 36deg slope. Ignore air resistance. a) What is Bond’s speed with respect to the ground at the takeoff point in m/s and mph? How realistic is this estimate and why? b) What is the location of the landing point with respect to the takeoff point?

You are present for the testing of the ride, in which an empty 250-kg car is sent along the entire ride. Near the end of the ride, the car is at near rest at the top of a 110-m tall track. It then enters a final section, rolling down an undulating hill to ground level. The total length of track for this final section from the top to the ground is 250 m. For the first 230 m, a constant friction force of 50.0 N acts from computer-controlled brakes. For the last 20 m, which is horizontal at ground level, the computer increases the friction force to a value required for the speed to be reduced to zero just as the car arrives at the point on the track at which the passengers exit. (a) Determine the required constant friction force for the last 20 m for the empty test car. (b) Find the highest speed reached by the car during the final section of track length 250 m. (c) You are…arrow_forward

The curved portions of the track are frictionless, but for the flat part the coefficient of kinetic friction is μk = 0.2 . The particle is released from rest at point A, which is at height h = L/ 2 .

Assume there is no friction. b)Determine the speed of the block after it has traveled 1.30 m along the plane, starting from rest. Assume the coefficient of friction between all surfaces is μ = 0.0370. Since the block is much lighter than the cylinder, ignore tension in the string when calculating the normal force on the cylinder.
