A 0.28 kg mass is held against a compressed spring with a spring constant of 2,446 N/m. The mass is initially at rest upon a horizontal surface and the spring force is directed parallel to the plane of the surface. If the coefficient of kinetic friction is 0.716, with what speed does the mass leave contact with the spring if the spring is initially compressed by 0.068 m?
Two identical springs, both of force constant k=200 N/m, are fixed at opposite ends of a level track. A 5.0 kg block is pressed against the left spring, compressing it by 0.15 m. The block (initially at rest) is then released. The entire track is frictionless except for the section between A and B. Given that the coefficient of friction between block and track is 0.08 and the length of AB is 0.25 m, determine where the block comes to rest, as measured from A. hord L m 1oooooooo m A
A horizontal spring on a frictionless surface with a spring constant of 50 N/m is compressed 0.4 m away from equilibrium and it is held at rest. A 5 kg mass is attached at the end of the spring. The spring-mass system is released from rest. Calculate the velocity of the mass when it is halfway back to its equilibrium position (0.2 m away).
A block of mass, 1.5 kg is attached and secured to an end of a spring with a spring constant of 10,000 N/cm. The other end of the spring is secured to the wall. The block is pushed against the spring, which compresses the spring to a position of x = -0.004 cm. When uncompressed, the end of the spring that is attached to the block is at a position of x = 0.00 cm. If possible, can you help me calculate the frictional force exerted on the block from -0.04 cm to 0.00 cm? Thank you.
