With what speed does the mass leave the spring?

The string on a bow can be described as a spring. A particular bow’s string has a spring constant of 110 N/m and is pulled back 0.6 m to launch a 0.02 kg arrow. If the bow has a mass of 1 kg, what will be the speed at which the arrow is launched?

A child's toy consists of a piece of plastic attached to a spring (as shown in Figure). The spring is compressed against the floor by 2.00 cm, and the toy is released. If the toy has a mass of 100 g and rises to a maximum height of 60.0 cm, estimate the force constant of the spring? Copyright © 2009, Raymond.

A cannon with a spring constant of 147 N/m is compressed by 20 cm to shoot marbles of mass 30 g. What is the farthest distance that it can shoot without hitting the top of the ceiling that is 3.0m above the ground?

A Spring is compressed 1.1 cm is found to launch a ball 8.0 m vertically in the air. If instead we want the ball to go up 72.0 M, by how much will we need to compress the spring. (enough info is provided) Write the answer to two demical places.   Can someone assist?

What is the minimum amount that the spring must be compressed if the car is to stay on the track? (answer in m)

A mass of 0.75 kg is suspended from a spring. If 1.41 J of work is done against the spring as the mass is pulled 0.15 m away from its equilibrium position, what is the spring constant of the spring?

A ball is attached to a vertical spring with a spring constant of 6.0 N/m.it is held at the equilibrium position of the spring and then released. it falls 0.40m and then bounce back up again. Calculate the mass of the ball

Problem 69. The light rod is pivoted at O and carries the 8 lb and 10 lb particles. If the rod is released from rest at 0 = 30° and swings in the vertical plane, calculate (a) The velocity v of the 8lb particle just before it hits the spring and (b) The maximum compression x of the spring. Assume that x is small so that the position of the rod when the spring is compressed is essentially vertical. 10 lb 18" www k = 150 lb/in. 8 lb

A marble with a mass of 0.085 kg compresses a spring 5.1 cm. If the spring has a constant k = 150 N/m, what will the velocity of the marble be when it's released?
