- As shown in the figure below, a box of mass m = 9.60 kg is slidine across a horizontal frictionless surface with an initial speed v, = 3.40 m/s when k = 2950 N/m. encounters a spring of constant The box comes momentarily to rest after compressing the spring some amount x Determine the final compression x (in m) of the spring. 0.2 Can you write an expression for the initial kinetic energy of the box in terms of its mass and initial speed? What is the final kinetic energy of the box? How is the change in kinetic energy related to the initial and final kinetic energy? Since only conservative forces are acting on the system (box and spring) is energy conserved? How is the change in spring potential energy related to the change in kinetic energy of the box? How is the compression of the spring related to the change in potential energy of the spring and the spring constant? mA freight company uses a compressed spring to shoot 1.70 kg packages up a 1.00-m-high frictionless ramp into a truck, as (Figure 1) shows.

- Please draw an LOL diagram. I gave an example of it.Solve using conservation of E. A 25 g ball, resting on a spring, compresses it 8.0 cm and is then launched up, reaching a height of 1.2m. Find k. Correct answer: 98 N/mThe figure below shows a force versus position graph for a spring/block system. If Fs=160N and the block is released at x = 12 cm (not shown on figure) how much work is done on the block by the spring as the block goes from x = + 8.0 cm to x = + 5.0 cm. HInt: Determine k from the graph. Don't forget to convert from cm.
