- A box slides down a plank of length d that makes an angle of θ with the horizontal as shown. μk is the kinetic coefficient of friction and μs is the static coefficient of friction. Enter an expression for the minimum angle θ (in degrees) the box will begin to slide. Enter an expression for the nonconservative work done by kinetic friction as the block slides down the plank. Assume the box starts from rest and θ is large enough that it will move down the plank. For a plank of any length, at what angle θ (in degrees) will the final speed of the box at the bottom of the plank be 0.55 times the final speed of the box when there is no friction present?

ThanksThe block is released from rest from the position in the picture and slides 6 meters down the frictionless incline. It strikes a spring that is at its natural length. Assume the spring is ideal and the mass of the spring is negligible. Mass of block = 20kg Incline is 30 degrees above horizontal spring constant = 200 N/m What is the max speed of the block? How far has the spring compressed when it reaches this max speed?
- Help with the following questionBelow is a conservation of energy problem. The solution to this problem is provided. Assess whether the solution provided is correct or incorrect AND EXPLAIN WHY. 1. A 4.6 kg block is at rest against a horizontal spring that is compressed by 0.40 m. The spring has a spring constant of k₁ = 2750 N/m. After leaving the spring, it travels up a 28° incline to a height of 2.8 m. At the top of the hill is a second spring with a spring constant of k₂ = 350 N/m. The horizontal portions are frictionless, but the hill has a coefficient of kinetic friction equal to uk= 0.16. x₁ = 0.40 m (CO))) N k₁ = 2750- m Simplifies to Mk = 0.16 a.

The value of the spring force constant is k= 50 N/m. There is no friction in the system. Use the work-energy theorem (chapter 6) to find the initial velocity, Vo, of the box.
- In the figure below the block has m = 3.0 kg and the spring has k = 350 N/m. If the block, initially at rest, is released from a height of 0.8 m, what is the maximum compression of the spring? Ignore friction.Question 7 m 0Q000 -Xo +Xo A block of mass m is on a rough horizontal surface and is attached to a spring with spring constant k. The coefficient of kinetic friction between the surface and the block is u. When the block is at position a = 0, the spring is at its unstretched length. The block is pulled to position I = +x0, as shown above, and released from rest. The block then travels to the left and passes through a = 0 before coming momentarily to rest at position a = Which of the following is a correct expression for the kinetic energy of the block as it first travels through position a=0? ka umgroYou have a spring of spring constant k, and a block of mass 0.200 kg. You set the spring up vertically and compress the spring 0.300 m. It launches the block up to a max height of 2.20 m. What is the spring constant?
