1) A block of mass m = 0.52 kg is 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.

A 2 kg block is launched to the right by a spring with k=1000 N/m. The spring is initially compressed by 0.3 m and is not attached to the block. It slides across the table a distance of 0.2 m where is hits and sticks to a 4 kg block. The 4 kg block is right at the end of a second, initially uncompressed, 1000 N/m spring. Find the maximum compression of the second spring if the coefficient of friction...

A 10-gm bullet traveling at 500 m/s passes through a 1-kg block and emerges with a speed of 100 m/s. The block is initially at rest on horizontal surface. a) The block slides 2.00 m before coming to rest. Find mu_k for this surface. b) If the block is on a frictionless surface, and attached to a spring with k = 400 N/m, find the distance, d, that the spring is compressed.

A 2.00 kg frictionless block is attached to a horizontal spring
as shown. Spring constant k = 200.00 N/m. At t = 0, the position x
= 0.225 m, and the velocity is 4.25 m/s toward the right in the
positive x direction. Position x as a function of t is: x =
A*cos(?t + theta) , where A is the amplitude of motion and ? is the

A block of mass m = 4.50 kg slides along a horizontal table with velocity vo = 5.00 m/s
A block of mass m = 4.50 kg slides along a horizontal table with velocity vo = 5.00 m/s. At x = 0, it hits a spring with spring constant k = 42.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by μ = 0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.
