A 0.500-kg object is connected to a horizontal massless spring. The spring is initially stretched by 0.200 m and the object is released from rest there. It proceeds to move without friction. The next time the speed of the object is zero is 0.500 s later. Determine the maximum speed of the object, the spring constant, and the mechanical energy of the system. Determine potential energy of the object when it’s speed is a third of the maximum speed.
A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released...
A mass of 5 kg is compressed 3.9 meters into one spring, held still, and released from rest. It travels over a horizontal surface, up an incline which has a height (not length) of 5 meters, and then travels over another horizontal surface. At the end of that surface is another spring with the same spring constant. The mass hits the second spring and eventually stops after compressing it 2.3 meters. What is the elastic potential energy of the second...

A block of mass m and speed v collides with a massless ideal spring that is initially un-stretched, compressing it by d. Instead of the previous values, suppose the mass of the block is 7m and its speed is v/7. In this new situation, what is the compression of the same spring? (Assume that no mechanical energy is lost during the collision and the subsequent motion of the system.) Select one: 0 d cross out 2.65d cross out O 0.2670...

Suppose that two carts, with a compressed spring between them (but not attached to either cart), are free to roll on a level table. The carts have very different masses and are initially stationary. Consider frictional losses to be negligible. The spring is released and the carts move apart. Are the final kinetic energies of the two carts equal, or is one greater than the other (if so, specify which is greater)? Explain your reasoning using fundamental physics principles, laws,...

A block of mass mis attached to a horizontal spring and rests on a flat, smooth surface as seen in the figure. The block can be pushed in the negative x- direction to compress the spring or pulled in the positive x-direction to stretch the spring. Where along the x-axis does the block have to be for the spring to have zero potential energy? Marked out of Flag estion ix=0 0 Select one: O a. The spring has zero potential...

A spring (k= 12 N/m), which can be stretched or compressed, lies flat on a frictionless table. One end of the spring is attached to the wall, and the other has a 3.3 kg mass attached. Assume the equilibrium position is labelled zero. A student pulls the mass out to x=14.0cm and releases it from rest at time t=0. The mass oscillates as a SHM. What is the speed of the mass at time t=14.4 s? Answer: Check

A mass is placed on a frictionless, horizontal table. A spring (k = 165 N/m), which can be stretched or compressed, is placed on the table. A 3-kg mass is anchored to the wall. The equilibrium position is marked at zero. A student moves the mass out to x = 7.0 cm and releases it from rest. The mass oscillates in simple harmonic motion. Find the position, velocity, and acceleration of the mass at time t = 3.00 s. Round...

A massless spring of a spring gun has a force constant k=800 N/m. A ball of mass 0.5 kg is resting on top of the spring. The ball compresses the spring by d as shown in the right figure. When the gun is fired vertically, the ball reached a maximum height of 5 m from the top of the spring as it returns to its natural length. Calculate how much the spring was initially compressed (d). (a) 12 cm; (b)...

Suppose a 0.270 -kg mass on a spring-loaded gun that has been compressed 0.210 m has elastic potential energy of 24.0 J. How high above the spring's equilibrium point can the gun fire the mass if the gun is fired straight up?
