I Review A 2.0-kg box rests on a plank that is inclined at an angle of 65 ° above the horizontal. The upper end of the box is attached to a spring with a force constant of 400 N/m, as shown in the figure(Figure 1). Part A If the coefficient of static friction between the box and the plank is 0.28, what is the maximum amount the spring can be stretched and the box remain at rest? Express your answer using two significant figures. ? cm Figure 1 of 1 Submit Request Answer < Return to Assignment Provide Feedback 2.0 kg 65

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
