In the figure, a 4.2 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. The block's initial speed is vo = 5.1 m/s, the height difference is h = 1.0 m, and μk = 0.632. Find d. d μ=0- h -μk

1- A 3 kg block pushes a spring of negligible mass and force constant k = 400 N / m to compress 0.22 m. When the block is released, it first travels on a frictionless horizontal ground and then climbs on an inclined plane with a slope of 37° and a kinetic friction %3D coefficient of µk = 0.1.

A vehicle applies it breaks for 102 ft before departing the roadway. The roadway surface friction factor is 0.50. The vehicle continues to break on an unpaved surface with a fiction factor of 0.30, for another 30 ft. The vehicle then strikes a stationary object with an impact of 20 mph. What was the initial speed of the vehicle? The roadway and unpaved surface are level.

Q: A truck (m = 10000 kg) is traveling at a speed of 30 m/s (about 70 mph) down the Kailua side of the Pali Highway when its brakes cut out. The truck driver quickly navigates to a "runaway truck ramp" to slow down enough that he can apply his emergency brakes. If the truck was originally at a height of 10.0m above the bottom of the "runaway truck ramp", and friction is negligible, how high up the ramp (height) does the truck need to go to come to a stop?
