**14. A 15.0-kg block rests on a horizontal table and is attached to one endof a massless, horizontal spring. By pulling horizontally on the other endof the spring, someone causes the block to accelerate uniformly and reacha speed of 5.00 m/s in 0.500 s. In the process, the spring is stretched by0.200 m. The block is then pulled at a constant speed of 5.00 m/s, duringwhich time the spring is stretched by only 0.0500 m. Find (a) the springconstant of the spring and (b) the coeffi cient of kinetic friction betweenthe block and the table.

A0.62 kg mass is held against the a compressed spring and released from rest. The linear spring is positioned horizontally across a frictionless surface. It has a spring constant of 609 N/m and is initially compressed by a distance of 0.134 m from its equilibrium position. With what speed does the mass leave the spring?
You attach your 4.58 - kg Physics for Engineers book to a horizontal spring (k = 549 N/m). You then pull the book to a distance of 6.7 cm and released it from rest. If the coefficient of kinetic friction between your book and the surface is 0.31, calculate the block's speed as it passes through its original position.
A block is hung from the end of a spring with spring constant 15 N/m and made to vibrate up and down with a maximum speed of 0.4m/s. The spring is held up by a force sensor, which is set to read 0N when the block is at rest on the end of the spring. The graph attached belwo shows the reading on the force sensor over time as the block vibrates. Plot the position-time and velocity-time graphs for the blocks as it vibrates. Explain with work and in words how you determined the shapes of these as well as their amplitudes.

A 50.0-g object is placed against the free end of a spring (k = 24.5 N/m) that is compressed 21.0 cm. Once released, LO000 the object slides a distance di = 1.55 m across the tabletop and eventually lands dz = 2.10 m from the edge of the table on the floor, as shown in the figure. The sliding distance on the tabletop includes the 21.0-cm compression of the spring, and the tabletop is h 1.00 m above the floor level. h Determine whether or not there is friction between the object and the table. If there is, determine the value of the kinetic friction coefficient . If there is not, enter 0.

You attach a 2.10 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by 0.300 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches a speed of zero again 0.100 s after release (for the first time after release). What is the maximum speed of the weight (in m/s)? 18.85 x Your answer is off by a factor of 2.
