K = 40N/m , total weight W = (5+2)×9.8 = 68.6N
Let compression is y.
Hence from Hook's law, W = ky
=) y = W/k = 68.6/40 = 1.715m
Now after removal of 5kg block, m = 2kg
Applying conservation of energy, U = K
=) 1/2 ky^2 = 1/2 mv^2
=) v = y √k/m = 1.715× √20 = 7.67m/s
=) v = 7.67m/s

A horizontal spring of spring constant 100 N/m is attached to a wall, and a block (A) of mass 5 kg. The block rests on a frictionless table.
3. A horizontal spring of spring constant 100 N/m is attached to a wall, and a block (A) of mass 5 kg. The block rests on a frictionless table. It oscillates with an amplitude of 10 cm. On top of the block rests a second block (B), held in place only by friction. (A) If block B slips, where is it most likely to do so: near the center of the spring's travel, or near the extremes? Why? (B) How...

A block of mass M = 0.400 kg is attached to a spring that initially rests on a frictionless, horizontal surface. A moving rifle bullet with mass m = 16.0 g strikes and embeds itself in the block. The impact compresses the spring by 28.0 cm. The spring constant of the spring is k = 455 N/m. What was the initial speed of the bullet?

A 0.500 kg block of wood rests on a horizontal frictionless surface and is attached to a spring (also horizontal) with a 29.5 N/m force constant that is at its equilibrium length. A 0.0600 kg wad of Play Doh is thrown horizontally at the block with a speed of 2.70 m/s and sticks to it. Determine the amount in centimeters by which the Play-Doh-block system compresses the spring.

A 0.30-kg block rests on a frictionless level surface and is attached to a horizontally aligned spring with a spring constant of 52.0 N/m. The block is initially displaced 3.20 cm from the equilibrium point and then released to set up a simple harmonic motion. What is the speed of the block when it passes through the equilibrium point?

A block with mass M = 6.0 kg rests on a frictionless table and is attached by a horizontal spring (k = 130 N/m) to a all.
A block with mass M = 6.0 kg rests on a frictionless table and is attached by a horizontal spring (k = 130 N/m) to a all. A second block, of mass m = 1.25 kg, rests on top of M. The coefficient of static friction between the two blocks is 0.30. What is the maximum possible amplitude of oscillation such that m will not slip off M?

A 5-kg collar A is at rest on top of, but not attached to, a spring with stiffness k1 = 400 N/m when a constant 150-N force is applied to the cable. Knowing A has a speed of 1 m/s when the upper spring is compressed 75 mm, determine the spring stiffness k2. Ignore friction and the mass of the pulley
