A 4.5 kg box slides down a 4.2-m -high frictionless hill, starting from rest, across a 2.2-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m . The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.2-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.22. Part C How far is the spring compressed? Express your answer...

In the figure below, block-2 of mass M = 1 Kg is at rest on a frictionless surface and touching the end of an un-stretched spring whose spring constant is 200 N/m. The other end of the spring is fixed to a wall. Block-1 of mass 2 Kg, travelling at speed v_1 = 4 m/s, collides with block-2 and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?

3.0 kg block slides down a frictionless ramp of height 3.0
meters starting from rest. it then traverses a 2.0 metter rough
patch with a coefficient of kinetic friction 0.35 It then gets to a
smooth area where it compresses a horizontal spring of spring
constant 50 n/m.

A ball of mass m = 2.50 kg, starting from rest, falls a vertical distance h = 55.0 cm before striking a vertically mounted spring, which is then compressed a distance y = 16.0 cm. a) Using conservation of energy, derive the algebraic expression (using symbols) for the spring constant using the provided information. Clearly indicate your chosen initial and final states either on the diagram or in words. b) Determine the spring constant using your algebraic expression from part...

Problem 11.56 A 4.5 kg box slides down a 4.3-m -high frictionless hill, starting from rest, across a 1.7-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 1.7-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.27. How far is the spring compressed? Express your answer to...

A block of mass 11.0 kg slides from rest down a frictionless 33.0° incline and is stopped by a strong spring with k = 2.80 ✕ 104 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?

. A 2.00kg block is moved from point A (at rest) a distance of 2.00 m to point B under the action of a variable force F(x) 10x + 6x2. Once in point B it is moving down 1.00 m through an 60.00 inclined frictionless surface until hit a spring (point C) as shown in figure. (The coefficient of kinetic friction between the block and the surface between A and B is 0.3 and the spring constant equal to 400...
