10. A snowboarder starts at the top of a 160. m tall hill with a velocity of 3.00 m/s. The portion of the hill covered with snow is essentially frictionless, but the flat, horizontal section at the base of the hill covered with mud is not. If the snowboarder masses in at 80.0 kg, and the coefficient of kinetic friction between board and mud is 0.750, how much distance is required for the snowboarder to come to rest?

6. A loaded 425 kg toboggan is traveling on smooth horizontal snow at 5.40 m/s when it suddenly comes to a rough region. The region is 8.00 m long and reduces the toboggan's speed by 1.50 m/s. (a) What average friction force did the region exert on the toboggan?  (b) What is the coefficient of kinetic friction between the toboggan and surface ?

#2) If a 10.0 kg weight is released from rest from the top of a 50.0m tall building and we neglect air resistance, what will be the magnitude of the final impact velocity when it hits the ground and the time it takes? If needed, use 9.80 m/s² for the magnitude of g. Report answers to 3 sig figs.

A child shoves a 4.6 kg block so that it starts traveling across a level floor with an initial velocity of 3.6 m/s.    If the coefficient of kinetic friction between the block and the floor is 0.29, how far will it travel before coming to rest?

A 10 m long vertical cannon is used to accelerate a 1.0 kg ball straight up into air. A constant force of 13.2N is used to access bowling ball length of the canon. what is the ball's approximate velocity as it leaves the canon assuming no energy loss to friction​

A boy coasts down a hill on a sled, reaching a level surface at the botfom With a speed of 7.7 pm/s . If the coefficient of frichoe betweenthe Sleds runners and sow is 0.045 and the together weigh l620 N, how far des the sled travel On the level surface befor e coming to rest? boy and sled

A 10N force is applied (pushed down) at a 37 degrees angle onto a Box at rest. The Box then reaches a speed of 30 m/s in 15 seconds along a frictionless surface. What is the mass of the Box in kg?

43. Consider a large truck carrying a heavy load, such as steel beams. A significant hazard for the driver is that the load may slide forward, crushing the cab, if the truck stops suddenly in an accident or even in brak- ing. Assume, for example, a 10 000-kg load sits on the flatbed of a 20 000-kg truck moving at 12.0 m/s. Assume the load is not tied down to the truck and has a coefficient of static friction of 0.500 with the truck bed. (a) Calculate the minimum stopping distance for which the load will not slide forward relative to the truck. (b) Is any piece of data unnecessary for the solution?

Hi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, what was the coefficient of kinetic friction between the player and the ground?

1. Nailed it! You and your friend Peter are putting new shingles on a roof pitched at 25⁰. You're sitting on the very top of the roof when Peter, who is at the edge of the roof directly below you, 5.0 meters away, asks you for the box of nails. Rather than carry the 2.5 kg box of nails down to Peter, you decide to give the box a push and have it slide down to him. If the coefficient of kinetic friction between the box and the roof is μ = 0.55, what initial speed should you give the box to have it gently come to rest right at the edge of the roof next to Peter? You 5.0 m Peter
