- A skier starts from rest at the top of a hill that is inclined at 10.0° with respect to the horizontal. The hillside is 190 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest? mMY NOTES ASK YOUR TEACHER A frictionless plane is 10.0 m long and inclined at 30.0°. A sled starts at the bottom with an Initial speed of 5.10 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 initlal speed of the second sled. m/sAn empty sled of mass 25 kg slides down a muiddy hill with a constant speed of 2.4 m/s The slope of the hill is inclined at an angle of 15 degrees with the horizontal. a. Calculate the frictional force on the sled as it slides down the slope b.Calculate the coefficient of friction between the sled and the muddy surface of the slope c. The sled reaches the bottom of the slope and continues of horizontal ground. Assume the same coefficient of friction. In terms of velocity and acceleration, describe the motion of the sled as it travels on horizontal ground.

Suppose a box enters a region of frictional floors, as seen in Fig. 3. x = 0 1 μ1 H₂ μ3 μ4 H5 μ6 d The box with mass m = 2 kg enters the region with initial speed vo= 10 m/s. Each of the frictional patches has a length of d = (10/19.62) m. The n-th frictional patch has a coefficient of kinetic friction given by µn. (a) What is the initial kinetic energy of the box? (b) If n = 0.5 for all n, how far does the block travel before stopping? Find the thermal energy of the system at the end of each patch traversed. (c) Do the same if n = n/5.

- At point A, the velocity of the 50-kg crate, is 5.13 m/s. If the coefficient of kinetic friction is 0.265, determine the speed (m/s) of the crate at point B. 10 m 50 kg 15°The block in the figure is given a push up the incline so that its initial velocity is 8.00 m/s. What distance along the incline (in m) does the block move before coming to rest? Assume the surface is frictionless, and 0 21.0⁰. = 3 02. A penguin on a sled starts from rest and slides down a 12.00 hill with a coefficient of sliding friction, pk, for 5.00 m.

- The kinetic friction force between a 58.0-kg object and a horizontal surface is 41.0 N. If the initial speed of the object is 26.0 m/s, and friction is the only force acting on the object, what distance will it slide before coming to a stop? m (round to the nearest whole number) Answer:The diagram shows a box moving down a green ramp, beginning from rest at the top of the ramp and ending at the bottom. The angle of the ramp's surface with the horizontal and the distance the box moves on the ramp from top to bottom are shown in the diagram. Given this information, how long does it take the box to reach the bottom of the ramp? Assume the surface of the ramp is frictionless and ignore air resistance. Use g = 9.81 m/s². Give your answer in units of seconds to two significant figures. When inputting your answer in the box below, enter a numerical value only (without the unit's symbol or name). Ax = 36 m 8 = 30°Two cars descended the sloping road at an angle of 30° where When the first car stopped completely because of a red light, the second car behind it 20 meters started to brake, but did not stop immediately until it finally hit the first car in front of it. The speed at which the second car applies the brakes is 18 m/s. What is the speed of the second car just as it hits car B if the coefficient of kinetic friction is 0.4?
