A 15.4-kg block rests on a horizontal table and is attached to one end of a massless, horizontal spring. By pulling horizontally on the other end of the spring, someone causes the block to accelerate uniformly and reach a speed of 6.34 m/s in 0.980 s. In the process, the spring is stretched by 0.188 m. The block is then pulled at a constant speed of 6.34 m/s, during which time the spring is stretched by only 0.0836 m. Find (a) the spring constant of the spring and (b) the coefficient of kinetic friction between the block and the table.

A 15.3-kg block rests on a horizontal table and is attached to one end of a massless, horizontal spring. By pulling horizontally on the other end of the spring, someone causes the block to accelerate uniformly and reach a speed of 7.81 m/s in 1.75 s. In the process, the spring is stretched by 0.171 m. The block is then pulled at a constant speed of 7.81 m/s, during which time the spring is stretched by only 0.0600 m. Find...

A 0.0392-kg bullet is fired horizontally into a 2.04-kg wooden block attached to one end of a massless, horizontal spring (k = 838 N/m). The other end of the spring is fixed in place, and the spring is unstrained initially. The block rests on a horizontal, frictionless surface. The bullet strikes the block perpendicularly and quickly comes to a halt within it. As a result of this completely inelastic collision, the spring is compressed along its axis and causes the...

A 0.55 kg block rests on a frictionless horizontal countertop, where it is attached to a massless spring whose k-value equals 23.0 N/m. Let x be the displacement, where x = 0 is the equilibrium position and x > 0 when the spring is stretched. The block is pushed, and the spring compressed, until xi = −4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a) What is the block's maximum speed (in m/s) after it...

A block of mass m = 0.53 kg attached to a spring with force constant 119 N/m is free to move on a frictionless, horizontal surface as in the figure below. The block is released from rest after the spring is stretched a distance A = 0.13 m. (Indicate the direction with the sign of your answer. Assume that the positive direction is to the right.) The left end of a horizontal spring is attached to a vertical wall, and...
