A spring with a spring constant of 366 N/m is compressed so it contains 18.7392 joules of elastic potential energy. A. How much is the spring compressed by? __________meters

10 cm long spring, with a spring constant of 27 N/m, is used to reload the ball in a pinball machine. The spring is compressed by 4.0 cm by a mechanism in the machine and then let go. a. Calculate the elastic potential energy stored in the spring A new spring is fitted into the machine. It only needs to be compressed by 3.0 cm to store the same amount of elastic potential energy as the previus spring. b. Calculate the spring constant of this new spring The owner of the game wants to double the potential energy stored in this new spring. c. Calculate the compression of the spring needed in order to achieve this

2. A spring that has spring constant k = 360 N/m is compressed by x = 9 cm. When the spring is released, all its energy is transferred to a 22 g marble ball.

The figure below shows a force versus position graph for a spring/block system.  If Fs=160N and the block is released at x = 12 cm (not shown on figure) how much work is done on the block by the spring as the block goes from x = + 8.0 cm to x = + 5.0 cm.  HInt:  Determine k from the graph.  Don't forget to convert from cm.

A block attached to a 15 N/m-spring constant spring moves on a frictionless horizontal surface, its position-vs-time graph is shown below. What is the total mechanical energy of the block-spring system, in Joules? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit x (cm) 20 is needed in your answer, it is already given in the question statement. 0 -20- ਲਈ 4 6 8 –t (s)

*Need help with B only* You have a spring with a spring constant 4710 N/m. A) If you want to store 165 J of energy in this spring should you compress it or stretch it? B) How far in cm would you have to compress this spring to store this energy?

A 3 kg block is held 3 meters above the free end of a relaxed massless vertical spring. The block is dropped from rest so that it falls vertically onto the spring and compresses it by a distance of 0.2 meters. Use energy conservation to find the spring constant. A.) 7412 N/m B.) 4704 N/m C.) 9725 N/m D.) 3128 N/m

Someone Suppose you are working on designing a t-shirt launch cannon that works via a spring mechanism and still want to launch that t-shirt to Smeone. If you plan to launch at 45 degrees, need a speed of 30 m/s and the cannon is 0.2 meters long... A. What is the final kinetic energy of the 2.0 kg t-shirt upon leaving the cannon? E. What must the spring constant be to reach this final speed? C. If instead you launched the t-shirt straight up, what maximum height would it reach?
