As shown in the figure below, a box of mass m = 6.00 kg is sliding across a horizontal frictionless surface with an initial speed vi= 2.40 m/s when it encounters a spring of constant k = 2350 N/m.

The box comes momentarily to rest after compressing the spring some amount xc. Determine the final compression xc (in m) of the spring.

A box of unknown mass is sliding with an initial speed vi = 5.70 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring d = 3.50 m long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.

A 2.00 kg block sliding on a horizontal surface makes contact with a spring, compressing the spring (the other end of the spring is attached to a rigid wall). At the instant of contact, the block has a speed of 12.0 m/s. The coefficients of static and kinetic friction between the block and the surface are 0.55 and 0.35, respectively. The spring constant of the spring is 100.0 N/m. a) Determine the maximum compression of the spring b) Determine the...

A.Your mass m=11 kg block slides down a frictionless ramp having angle theta=0.51 radians to the horizontal. After sliding down the ramp a distance L=16 m the block encounters a spring of spring constant k=551 N/m. The spring is parallel to the ramp. Use g=9.74 m/s/s for the acceleration of gravity. Calculate the maximum compression of the spring, in meters. Include labeled diagrams showing the initial and final configurations, and a discussion of the solution method based on energy conservation....

In the figure, block 2 (mass 1.60 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 128 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 1.70 kg), traveling at speed v1 = 5.80 m/s, collides with block 2, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?
