A 75-kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28 degree incline. After sliding down the 110-m-long incline (on which the coefficient of kinetic friction is μk= 0.17), the snowboarder has attained a velocity v. The snowboarder then slides along a flat surface (on which μk= 0.14) and comes to rest after a distance x. Determine BOTH the snowboarder's acceleration on the incline AND his acceleration on the flat surface. Then, determine x.

Express answers in significant figures and scientific notation only. An athlete slides down from rest 40.0 meter along an icy hill which is 35 degrees from the horizontal. He then continues sliding on the level ice. a) If the coefficient of kinetic friction between the athlete and ice is 0.20 (neglect air resistance) find speed (m/s) of the athlete at the foot of the plane. b) find the distance (m) from the foot of the plane to the point where he has landed to the level ice
A 75-kg snowboarder has an initial velocity of 5 m/s and slides down a 92-m-long straight incline from an initial height 54 m and finally comes to rest after sliding horizontally a distance x.

A skier slides down a hill in a straight line. The hill is 60m high and the coefficient of kinetic friction between the snow and the skis is 0.1. The hill is at an angle of 10 degrees with the horizontal. The mass of the skier is 70 kg. If the skier starts her run from rest and air friction can be ignored, how fast is she moving at the bottom of the hill? Please answer in units of m/s.
A penguin slides at a constant velocity of 1.4 m/s down an icy incline. The incline slopes above the horizontal at an angle of 6.9?degrees. At the bottom of the incline, the penguin slides onto a horizontal patch of ice. The coefficient of kinetic friction between the penguin and the ice is the same for the incline as for the horizontal slope. How much time is required for the penguin to slide to a halt after entering the horizontal patch of ice?
A 1370-kg car is skidding to a stop along a horizontal surface. The car decelerates from 27.6 m/s to a rest position in 3.15 seconds. Assuming negligible air resistance, determine the coefficient of friction between the car tires and the road surface.
One way to determine the coefficients of friction (μs and μk) between two surfaces is to use an incline plane. Consider a block of mass m = 2.0kg initially at rest at the top of the ramp. The angle θ is increased slowly. The object starts to slide down the ramp when θ = 40 . Once the block slides down, the angle is kept constant. The block travels along the ramp by distance d = 2.0 m in time t = 1.5 s. (a) Determine the value of μs(b) Determine the value of μk
A mass m slides up an incline (with = 32.1 degrees above the horizontal) until it stops momentarily because of friction. The coefficient of static friction between the mass and incline is 0.9; the coefficient of kinetic friction between the mass and incline is 0.4. At a given instant, the mass is moving with speed of 4.3 m/s up the incline. How far beyond this point along the incline will the mass move before it comes to a stop?
An object moves with an initial speed of 5.01 m/s. It then enters a region with friction causing the object to come to rest after moving 2.56 m. What is the coefficient of friction?
A frictionless plane is 10.0 m long and inclined at 42.0°. A sled starts at the bottom with an initial speed of 5.70 m/s up the incline. When the sled reaches the point at which it momentarily stops, a second sled is released from the top of the incline with an initial speed v. Both sleds reach the bottom of the incline at the same moment. (a) Determine the distance that the first sled traveled up the incline. (b) Determine the initial speed of the second sled.

The brakes on a big truck fail and it is forced to use a runaway truck lane. The lane is perfectly horizontal, and full of deep gravel, creating a coefficient of kinetic friction between the truck and the gravel of 0.80. The truck enters the lane at moving 35 m/s (about 80 mph). How far does the truck travel before it stops?
