A spring with spring constant 28 N/m is compressed a distance of 9.0 cm by a ball with a mass of 201.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 9.0 cm and is also released, leaving the spring at point A. Assume the ball rolls, but ignore other effects of friction. (Assume that the ball is a solid ball.)   (a) What is the speed of the ball at point B?

A block with a mass m = 7.80 kg is attached to a lightweight spring with a spring constant k = 100 N/m that is attached to a wall. Initially the block is at rest and the spring is relaxed, as shown in figure (a). A second block with a mass mg = 7.00 kg is pushed up against block m, compressing the spring a distance A = 0.210 m, as shown in figure (b). The two blocks are released from rest, and both start moving to the right with negligible friction. IS a (a) When block m, reaches the equilibrium point, as shown in figure (c), block m, loses contact with block m,. Block m, continues to move right at a speed v. What is the speed v (in m/s)? m/s (b) Block m, continues to move right, reaching the point where the spring is at the maximum stretch (for the first time), as shown in figure (d). At this point, what is the distance D between the two blocks (in cm)? (Assume the widths of the blocks are much smaller than D.) cm

A 0.454-kg block is attached to a horizontal spring that is at its equilibrium length, and whose force constant is 23.0 N/m. The block rests on a frictionless surface. A 5.90×10−2-kg wad of putty is thrown horizontally at the block, hitting it with a speed of 8.96 m/s and sticking.How far does the putty-block system compress the spring?

A 0.650 kgkg block is attached to a spring with spring constant 14.0 N/mN/m. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 46.0 cm/scm/s. What is the block's speed at the point where x=0.20 A?

The class I'm taking is physics for scientists and engineers! I am completely stuck. Need help. I have attached the problem. Please view both attachments before answering. If you can please explain your answer so I can fully understand. Thank you!

2. A 1.2 kg cart moving at 6.0 m/s [E] collides with a stationary 1.8 kg cart. The head-on collision is completely elastic and is cushioned by a spring. b)The maximum compression of the spring during the collision is 2.0 cm. Find the spring constant. do it correctly please and thank you

Doing some physics homework and am kind of stumped here!

Need solution ANSWER: (a) 3.33 m/s (b) 389.40 m/s
