You need to make a spring scale to measure the mass of objects hung from it. You want each 1.0 cm length along the scale to correspond to a mass difference of 0.10 kg. What should be the value of the spring constant?
As shown below, a 3 kg block on a frictionless horizontal surface is attached to a cable and a 526 N/m spring. The block is in equilibrium (Fnet = 0) and the cable has a tension of 16 N. Determine the normal force on the block and how much the spring stretched. FN l=| x
A spring with a force constant of 300 N/m is attached to and compressed by a 4 kg mass to a compression of 1.5 m. The mass is released from rest. The surface is frictionless. How much time does it take the mass to return to the equilibrium position the first time after release? What is the velocity of the mass when it returns to the equilibrium position the first time after release? Include sign.

One way to measure the speed of a bullet is to fire it into a block of wood attached to a spring. The bullet hits the block and remains lodged in it. The spring is compressed after the collision. If the mass of the bullet is 8.0×10−38.0×10−3 kg, and the mass of the block is 4.0 kg, and the spring constant is 2400 N/m, then what is the initial speed of the bullet if the maximum compression of the spring is 0.087 m? Give your answer in m/s.
