A 0.85 kg block slides 3.3 m across a frictionless, horizontal table at 2.2 m/s, moving left. Once the block hits the spring, it sticks, compressing the spring 70 cm before the block stops and reverses direction. The block then continues to bounce back and forth, still attached to the spring. The spring constant is 8.4 N/m. Ignore air resistance.

(b) [3 points] Plot the velocity of the block as a function of time, with t = 0 when the block is 3.3 m away from the spring, sliding across the table. Use the same coordinate system and plot two full oscillations of the spring.

A 2.00-kg block lies at rest on a frictionless table. A spring, with a spring constant of 100 N/m, is attached to the wall and to the block. The second block of 0.50 kg is placed on top of the first one. The 2.00-kg block is gently pulled to a position x = + A and released from rest. There is a coefficient of friction of 0.45 between the two blocks. (a) Assuming that the top block does not slide,...

A block of mass ?=4.80 kg slides along a horizontal table with velocity ?0=3.00 m/s. At ?=0, it hits a spring with spring constant ?=36.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.350. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.

A block of mass M = 5.80 kg, at rest on a horizontal frictionless table, is attached to a rigid support by a spring of constant k = 6250 N/m. A bullet of mass m = 8.30 g and velocity of magnitude 570 m/s strikes and is embedded in the block (the figure). Assuming the compression of the spring is negligible until the bullet is embedded, determine (a) the speed of the block immediately after the collision and (b) the...
