A 25.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30.0 ◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.400 and the constant of the spring is k = 5000 N/m. How far does the crate compress...

A box with a mass of 8.67 kg slides up a ramp inclined at an angle of 28.3° with the horizontal. The initial speed is 1.66 m/s and the coefficient of kinetic friction between the block and the ramp is 0.48. Determine the distance the block slides before coming to rest. m As shown in the figure below, a box of mass m = 35.0 kg is sliding along a horizontal frictionless surface at a speed vi = 5.55 m/s...

oblem 2: A 5-kg box slides down a ramp. The ramp is l m in length and inclined at an angle of 30° as shown. The box starts from rest at the top. The surface friction coefficient is 0.25 1. Use energy methods to determine the speed of the box at the bottom of the ramp 2. How far does the box slide before stopping on the horizontal floor if it continues to experience the same friction coefficient. 1.00 m...

The answer is A. But why?
11. A crate first slides up an inclined ramp (0'< θ < 90'), momentarily comes to rest, and then slides back down the ramp. There is friction between the crate and the ramp. h of the following statements is true? A. The magnitude of the block's acceleration is greatest as it travels up the ramp. B. The magnitude of the block's acceleration is the same going up or down the ramp. C. The magnitude...

Chewbacca is pushing a 250 kg crate up a ramp, which is 26 degrees above the horizontal, into the Millenium Falcon. He managed to push the crate 11.4 m up the ramp when he spots some enemy bounty hunters. Chewbacca tries to defend himself by shooting at them and the crate starts sliding down the ramp. The coefficient of kinetic friction is 0.45. What is the work due to kinetic friction on the crate? What is the gravitational potential energy...

A crate of fruit with a mass of 39.5 kg and a specific heat capacity of 3750 J/(kg⋅K) slides 7.70 m down a ramp inclined at an angle of 37.9 degrees below the horizontal. 1. If the crate was at rest at the top of the incline and has a speed of 3.00 m/s at the bottom, how much work Wf was done on the crate by friction? Use 9.81 m/s2 for the acceleration due to gravity and express your...

A 9.00 meter long ramp is inclined at an angle of 6.00 above horizontal. A 7 kg box is given an intial push at the bottom of the ramp so that when it gets to the top it stops. The coefficient of kinetic friction between the box and the ramp is .230 a) what is the initial speed of the box just as it is pushed. (The answer is 7.68 m/s, but I can't seem to set it up properly...

A flat inclined plane of steel at 16 degrees from horizontal has a rectangular crate of wood weighing 27kg resting on it. What is the minimum coefficient of static friction between the crate and steel will the crate not slide? If the crate is accelerating upward at 1.1 m/s^2, and the coefficient of kinetic friction is 0.17 and the force on the crate is horizontal what is its magnitude?
