A 5.3 kg box is sliding down a hill. The hill is not very steep; its slope is 15o. The coefficients of friction between the box and the hill are μs=0.45 and μk=0.31. If the box starts with a speed of 3.7 m/s, how far down the hill does it travel?
5, Some of the funniest videos on the web involve motorists sliding uncontrollably on icy roads. Here let's compare the typical stopping distances for a car sliding to a stop from an initial speed of 10.0 m/s on a dry horizontal road, an icy hori- zontal road, and (everyone's favorite) an icy hill. (a) How far does the car take to slide to a stop on a hori- zontal roadi if the coefficient of kinetic friction is = 0.60, which...
Slanted surfaces with friction: A box is sliding down an incline tilted at a 12.0° angle above horizontal. The box is initially sliding down the incline at a speed of 1.50 m/s. The coefficient of kinetic friction between the box and the incline is 0.340. How far does the box slide down the incline before coming to rest? a) Draw Free Body diagrams for the two masses b) Write the equations for the two masses in the direction of motion...
Problem #3 In the diagram below, m; = 0.60 kg is sliding down the incline with an initial speed of 2.5 m/s and ma is initially motionless. mslides through distance d = 1.50 m before colliding elastically with m2 -0.80 kg. m2 later comes to rest my moves frictionlessly, and the coefficient of kinetic friction between me and the incline is 0.70. (a) A diagram illustrating the initial “situation of interest" is given below. Draw diagrams illustrating all other relevant...
A 107 kN crate slides down a ramp inclined at 11.1 degrees above horizontal. The initial speed of the crate is 4.13 m/s. The coefficient of kinetic friction between crate and ramp is 0.270. How far will the crate slide before coming to rest, in meters?
Our favorite crate full of armored armadillos is sitting at the bottom of a hill that is inclined 41° above the horizontal. The crate is 75 kg and the coefficient of kinetic friction between the crate and the ground is 0.31. Samer decides to drag the crate to the top of the hill, which is 20 m above the base of the hill. Samer attaches a thin rope to the crate so that when he pulls, the rope will be...
Some sliding rocks approach the base of a hill with a speed of 17.0 m/s . The hill rises at 42.0 ∘ above the horizontal and has coefficients of kinetic and static friction of 0.450 and 0.550, respectively, with these rocks. Start each part of your solution to this problem with a free-body diagram. Find the acceleration of the rocks as they slide up the hill. Once a rock reaches its highest point, will it stay there or slide down...
4 A Sliding Crate of Fruit Consta A crate of fruit with a mass of 38.0 kg and a specific heat capacity of 3600 J/(kg . K) slides 8.50 m down a ramp inclined at an angle of 37.0 degrees below the horizontal. Part A f the crate was at rest at the top of the incline and has a speed of 2.30 m/s at the bottom, how much work Wi was done on the crate by frict Use 9.81...
Th figure below shows a mass m=1.0 kg which is initially moving with speed v=6.9 m/s at the top of a frictionless hill of height h=4.7 m. It slides down the hill until it encounters a flat section with unknown coefficient of kinetic friction Uk. If the object travels a distance D=11.9 m before reaching a speed of v/2, what is the coefficient of kinetic friction uk? D Select one: O 0.44 O 0.60 O 0.33 O 0.38 O 0.55
Question 7 1 pts A rock is sliding down a hill. Assume that the hill is 20 meters high and the rock has a mass of 1,000 kilograms. If the rock started at the top of the hill with no initial speed, how much is its kinetic energy when it reaches the bottom of the hill? Use g=10 m/s2. Give the answer in kilojoules.
