Initially a 4kg mass and a 2kg mass are at rest on a friction free surface held together by a string. Between these two masses is a spring compressed by 0.1 m. At t= 0 , the string is cut and the two masses allowed to fly apart. When the masses are far apart, the velocity of the 2kg mass is 2m/s. 1) What is the velocity of the 4kg mass?? 2) Is momentum conserved in this process, i.e is...

(2) A block of mass m = 2kg, slides on a horizontal surface and collides with a spring of force constant 200N/cm. The block compresses the spring 6.16cm from the un-stretched position. Mechanical energy in the amount of 200m) is dissipated due to friction as the block is brought to rest. What was the speed of the block at the instant of collision with the spring? (5-points)

A bullet with mass 25g and initial horizontal velocity 320m=s strikes a block of mass 2kg that rests on a frictionless surface and is attached to one end of a spring. The bullet becomes embedded in the block. The other end of the spring is attached to the wall. The impact compresss the spring a maximum distance of 25cm. After the impact, the block moves in simple harmonic motion. 1. What is the frequency of the oscillation? 2. Sketch graphs...

1. A 2kg cubical cat slides on a horizontal surface 5m/s | 2kg- The surface is frictionless except in a 4111-wide patch, where the coefficient of kinetic friction is f = 0.2. The block is moving at 5m/s before it hits the patch. Take g = 10m/s, for simplicity. (a) What is the kinetic energy before the block hits the patch? (b) What is the work done by friction on the patch? (c) What is the kinetic energy after the...
