A force of 200 newtons stretches a spring 2 meters. A mass of 50 kg is attached to the end of aspring and is initially released from the equilibrium position with an upward velocity of 10 m/s. Find the equation of motion.

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 Huntress fires a bullet into a 3-kg wooden block resting on a smooth surface, and attached to a spring of spring constant 715. N/m. The bullet, whose mass is 7 g, remains embedded in the wooden block. She measures the maxumum distance that the block compresses the spring to be 4.50 cm. What is the speed of the bullet (in m/s)? (So the block is at equalibrium on a horizontal surface with a spriing attatched to the one side, which is then attatched to the wall. What equation am I able to use to find the speed of the bullet?)

A stiff spring k = 666 N/m has be attached to the floor vertically. A mass of 6.66 kg is placed on top of the spring as shown below and it finds a new equilibrium point. If the block is pressed downward and released it oscillates. If the compression is too big, however, the block will lose contact with the spring at the maximum vertical extension. Draw a free body diagram and find that extension at which the block loses contact with the spring.

A mass of 0.50 kg is held against compressed spring and released from rest while upon a horizontal, frictionless surface. The spring constant of the spring is 790 N/m and the mass leaves the spring with a speed of 7.84 m/s. Assume that the spring pushes the mass across the surface. By what amount was the spring initially compressed relative to its equilibrium position? 0.197

A 2.00­kg block is pushed against a spring with negligible mass and force constant k = 435 N/m , compressing it 0.215 m. When the block is released, it moves along a frictionless, horizontal surface. Find its velocity after the release?

A 5.75-kg mass stretches a vertical spring 0.5 m. If the spring is stretched an additional 1 m and released, how long does it take to reach the (new) equilibrium position again? (How do I find the amount of time?)

An object has a mass of 0.5 kg is placed in front of a compressed spring. When the spring was released, the 0.5kg object collides with another object with mass 1.5kg and they move together as one unit. Find the velocity of boxes if the spring constant is 40N/m, and spring. was initially compressed by 20cm. Answer with text and/or attachments:

A spring with a spring constant of 112 N/m has a mass hung on it so that it stretches 1.2 cm.  Calculate how much mass the spring is supporting.
