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...

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 20 kg crate is allowed to slide down a 60-m long smooth inclined plane which is 30° with the horizontal. At the bottom of the inclined plane, the crate is allowed to slide horizontally with the ground where the coefficient of friction between the crate and the ground is 0.15. After 1 m, the crate would meet a coil with a spring constant of 1000 N/m. (Assume that the friction no longer acts as the crate hits the spring).Calculate...

A 1 kg block slides down an inclined plane which makes an angle of 30degree to the horizontal. Starting from rest, it is found to have a speed of 3 m/s after it has moved through a distance of 1.6 m. Find the amount of mechanical energy dissipated due to friction as the block slides down the plane, and hence find the coefficient of friction between the block and the plane, Explain your steps and reasoning. Remember to draw a...

A skier of mass
m started at rest and slides down over a
frictionless inclined plane. He reached the bottom at a speed of 20
m/s. Then reached the second inclined plan. If the second inclined
plane has a friction coefficient of 0.2 and inclined at angle of
20°. How far does he slide on it before coming momentarily to
rest?

A block with mass m = 5.00 kg slides down a surface inclined 36.9 ∘ to the...
A block with mass m = 5.00 kg slides down a surface inclined 36.9 ∘ to the horizontal (the figure (Figure 1)). The coefficient of kinetic friction is 0.25. A string attached to the block is wrapped around a flywheel on a fixed axis at O. The flywheel has mass 25.0 kg and moment of inertia 0.500 kg⋅m2 with respect to the axis of rotation. The string pulls without slipping at a perpendicular distance of 0.200 m from that axis. A)...

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...
