An object with a mass of 10 kg is initially at rest at the top of a frictionless inclined plane that rises 30° above the horizontal. At the top, the object is initially 8.0 m from the bottom of the incline, as own in the figure. When the object is released from this position, it eventually stops at a distance from the bottom of the inclined plane along a horizontal surface, as shown. The coefficient of netic friction between the horizontal surface and the obiect is 0 20 and air resistance is negligible

A bicyclist can coast down a 8.18 degree hill at a constant speed of 5.55 km/h. If the force of air resistance is proportional to the speed v so that Fair = c v, calculate the average force (in N) that must be applied in order to descend the hill at 19.3 km/h. The mass of the cyclist plus bicycle is 78.6 kg.
A 5 kg box sits at rest at the bottom of a ramp that is 8 m long and that is inclined at 30° above the horizontal. Thecoefficient of kinetic friction is 0.40 and the coefficient of static friction is 0.50. What constant force, appliedparallel to the surface of the ramp is required to push the box to the top of the ramp in a time of 4 s?
A 6.0-kg block initially at rest is pulled to the right along a frictionless, horizontal surface by a constant horizontal force of magnitude 12 N. Find the block’s speed after it has moved through a horizontal distance of 3.0 m.
A skier starts from rest at the top of a hill that is inclined 10.5°with respect to the horizontal. The hillside is 2.00 x 102 m long,and the coefficient of friction between snow and skis is 0.075 0.At the bottom of the hill, the snow is level and the coefficientof friction is unchanged. How far does the skier glide along thehorizontal portion of the snow before coming to rest?
A 2.20 kg block is initially at rest on a horizontal surface. A horizontal force of magnitude 4.83 N and a vertical force are then applied to the block (Fig. 6-17). The coefficients of friction for the block and surface are µs = 0.4 and µk = 0.25. Determine the magnitude of the frictional force acting on the block if the magnitude of is (a) 8.00 N and (b) 12.0 N. (The upward pull is insufficient to move the block vertically.)
A snowboarder takes speed downhill in order to get up a hill without pushing. If he arrives at the bottom of the hill with a velocity of 60 km/h, will he be able to get up a hill 75 m long with an 8% slope? (Kinetic friction coefficient: snowboard-snow = 0.1 and air resistance is neglected). (Hint: a 1% slope rises 1 m vertically for every 100 m oflateral travel.)
An object (m = 2.08 Kg) moving on a horizontal surface reaches the bottom of an incline with a speed of 4.18 m/s. The incline makes an angle of 37.0 degrees with respect to the horizontal. The coefficient of kinetic friction between the box and the inclined surface is 0.300. How far up the inline will the object move before coming to stop?
1200-kg car is coasting down a 30° hill as shown in Fig. 6-4. At a time when the car's speed is 12 m/s, the driver applies the brakes. What constant force F (parallel to the road) must result if the car is to stop after traveling 100 m?
Largely because of riding in cars, you are used to horizontal circular motion. Vertical circular motion would be anovelty. In this sample problem, such motion seems todefy the gravitational force.In a 1901 circus performance, Allo “Dare Devil”Diavolo introduced the stunt of riding a bicycle in a loopthe-loop (Fig. 6-9a). Assuming that the loop is a circle withradius R 2.7 m, what is the least speed v that Diavolo andhis bicycle could have at the top of the loop to remain incontact with it there?
In Fig. 6-45, a 1.34 kg ball is connected by means of two massless strings, each of length L = 1.70 m, to a vertical, rotating rod. The strings are tied to the rod with separation d = 1.70 m and are taut. The tension in the upper string is 35 N. What are the (a) tension in the lower string, (b) magnitude of the net force on the ball, and (c) speed of the ball? (d) What is the direction of ?
A 5.00 kg block is thrown up an inclined plane with an initial speed of 8.00 m / s which stops after traveling 3.00 m along the plane, which is inclined at an angle of 30 , 0 ° from the horizontal. For this motion determine the coefficient of kinetic friction between the block and the surface.
