A spring is resting vertically on a table. A small box is dropped onto the top of the spring and compresses it. Suppose the spring has a spring constant of 500 N/m and the box has a mass of 2.8 kg. The speed of the box just before it makes contact with the spring is 0.55 m/s. (a) Determine the magnitude of the spring’s displacement at an instant when the acceleration of the box is zero. (b) What is the...

Problem 2.43 Your answer is partially correct. Try again. Use the approximation that Vavg -Plm for each time step. A block is attached to the top of a spring that stands vertically on a table. The spring stiffness is 58 N/m, its relaxed length is 31 cm, and the mass of the block is 395 g. The block is oscillating up and down as the spring stretches and compresses. At a particular time you observe that the velocity of the...

Chapter 09, Problem 048 Your answer is partially correct. Try again Particle A and particle are held together with a compressed spring between them. When they are released, the spring pushes them apart and they then fly off in opposite directions, free of the spring. The mass of A is 2.00 times the mass of , and the energy stored in the spring was 80 ). Assume that the spring has negligible mass and that all its stored energy is...
