A vertical spring with a spring constant of 400 N/m is mounted on the floor. From directly above the spring, which is unstrained, a 0.30 kg block is dropped from rest. It collides with and sticks to the spring, which is compressed by 2.7 cm in bringing the block to a momentary...

A block (mass m) hangs from a spring (spring constant k). The block is released from rest a distance d above its equilibrium position. (a) What is the speed of the block as it passes through the equilibrium point? (Use any variable or symbol stated above along with the ...

A 0.150 block moving vertically upward collides with a light vertical spring and compresses it 4.50 before coming to rest. If the spring constant is 54.0 , what was the initial speed of the block? (Ignore energy losses to sound and other factors during the collision.)

A horizontal spring attached to a wall has a force constant of 800 N/m. A block of mass 1.10 kg is attached to the spring and oscillates freely on a horizontal, frictionless surface as in the figure below. The initial goal of this problem is to find the velocity at the ...

A 11.0 g bullet is fired horizontally into a 108 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring of constant 151 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum...

A spring that has a force constant of 1100 N/m is mounted vertically on the ground. A block of mass 1.90 kg is dropped from rest from height of 1.65 m above the free end of the spring. By what distance does the spring compress?

physics
A block of weight w = 35.0 N sits on a frictionless inclined plane, which makes an angle theta = 27.0 degrees with respect to the horizontal. A force of magnitude F = 15.9 N, applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. ...
