- 1. Sam, whose mass is 75 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 200 N and a coefficient of kinetic friction on snow of 0.10. Unfortunately, the skis run out of fuel after only 10 s. A. What is Sam’s top speed? B. How far has Sam traveled when he finally coasts to a stop?5. A top WNBA player can jump about .7 meters off the ground. If her mass is 50 kg, what force must she exert against the ground? Assume she crouches a distance of .2 metes prior to jumping, and thus the upward force has this distance to act before leaving the ground. 6. A block is given an initial speed of 4 meters per second up the 0 = 22° plane shown below. Ignoring friction, %3D (a) how far up the plane will it go? (b) How much time elapses before it returns to its starting point? R 4m/s s 22°A 0.12 kg egg is dropped from a height of 2m and falls into an egg catcher.a.

- A ramp is inclined at an angle of 30°. A 5 kg block has an initial speed of 8 m/s up a ramp. It comes to rest after traveling 3 m. There is friction between the block and the ramp. a. Draw the free body diagram for the block. b. What is ∆K for the block? c. What is ∆Ugrav for the block? d. What is the work done by friction? e. What is the work done by the normal force? f. What is the coefficient of kinetic friction? g. The coefficient of static friction is 0.7. After the block comes to rest, does it start sliding down the ramp, or does it remain fixed in position? Explain your reasoning and state how much friction acts on the block. Draw the free body diagram.At the start of a race, a four-man bobsled team pushes their sled as fast as they can along a 50 m flat starting stretch. The net force that the four men together apply to the 325 kg bobsled is 80.093 N directed at 15 degrees below the horizontal. As they push, 60 N of kinetic friction opposes them. What is the speed of the sled right before the team jumps on the sled?Fundamentals of Physics, 11th Edition, Custom WileyPLUS Course for West Help | System Announcements PRINTER VERSION 1 BACK NEXT Chapter 08, Problem 057 GO In the figure, a 3.9 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d.
