A 55 kg skateboarder wants to just make it to the upper edge of a “half-pipe” with a radius of 3.0 m, as shown. What speed does he need at the bottom if he will coast all the way up? The skateboarder isn’t a simple particle: Assume that his mass in a deep crouch is concentrated 0.75 m from the half-pipe. If he remains in that position all the way up, what initial speed does he need to reach the upper edge?
Two blocks are connected by a light string that passesover a frictionless pulley as in Figure P5.38. The system is released from rest while m 2 is on thefloor and m1 is a distance h above thefloor. (a) Assuming m 1 >m 2, find anexpression for the speed of m1 justas it reaches the floor. (b) Takingm 1 = 6.5 kg, m 2 = 4.2 kg, andh = 3.2 m, evaluate your answer topart (a), and (c) find the speed ofeach block when m 1 has fallen a distanceof 1.6 m.

A child of mass m starts from rest and slides without friction from a height h along a curved waterslide (Fig. P5.46). She is launched from a height h/5 into the pool. (a) Is mechanical energy conserved? Why? (b) Give the gravitational potential energy associated with the child and her kinetic energy in terms of mgh at the following positions: the top of the waterslide, the launching point, and the point where she lands in the pool. (c) Determine her initial speed V0 at the launch point in terms of g and h. (d) Determine her maximum airborne height ymax in terms of h, g, and the horizontal speed at that height, v0x. (e) Use the x-component of the answer to part (c) to eliminate from the answer to part (d), giving the height ymax in terms of g, h, and the launch angle . (f) Would your answers be the same if the waterslide were not frictionless? Explain. Figure P5.46
A 59.0 kg skateboarder wants to just make it to the upper edge of a "quarter pipe," a track that is one-quarter of a circle with a radius of 3.20 mWhat speed does he need at the bottom?
You're standing at the top of a snow-covered hill, sloped at 20.0°. The coefficient of kinetic friction between your sled and the hill is 0.534. Unfortunately, there's a running stream just at the bottom of the hill, and you don't want to get wet. If you and your sled together have a mass of 87.0 kg, with what speed should you push off with to stop just before the stream, 77.0 m down the slope?
A motorcycle daredevil plans to ride up a 2.0-mm-high, 20∘∘ ramp, sail across a 10-mm-wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as he starts up the ramp. He is going 10.4 m/sm/s at that instant, and the rolling friction of his rubber tires (coefficient 0.02) is not negligible. Justify your answer by calculating the distance he travels through the air after leaving the end of the ramp. x =
Carol wants to move her 32kg sofa to a different room in the house. She places "sofa disks", slippery disks with mu k =.080 , on the carpet, under the feet of the sofa. She then pushes the sofa at a steady.4 .4 m/s across the floor. How much force does she apply to the sofa?
A 97.49-kg skier with an initial speed of vi=34.93 m/s coasts up a H=11.75-m-high risel. The slope angle is theta=27.25. What is her final speed at the top? Assume the coefficient of friction between her skis and the snow is 0.035 (Hint: Find the distance traveled up the incline assuming a straight-line path as shown in the figure.) Use g = 10 m/s2.
