4.) A light horizontal spring (k=4000 N/m) is compressed 10 centimeters from its relaxed state by a 3 kg mass on the left, and a 5 kg mass on the right, which are initially at rest. The spring then is allowed to relax, pushing the masses apart. A.) Calculate the final total kinetic energy of this system (i.e. both masses). (20 J) B.) Determine the final velocity of each mass when the spring relaxes. Assume friction is negligible.

A light spring of force constant 3.90 N/m is compressed by 8.00 cm and held between a 0.250 kg block on the left and a 0.520 kg block on the right. Both blocks are at rest on a horizontal surface. The blocks are released simultaneously so that the spring tends to push them apart. Find the maximum velocity each block attains if the coefficient of kinetic friction between each block and the surface is the following. In each case, assume...

A 2.1.0-kg block is accelerated from rest by a compressed spring (ks = 545 N/m). The block leaves the spring at the spring’s relaxed length. The block then travels along a rough horizontal with a coefficient of kinetic friction μk = 0.240 a distance of x = 6.90 m before frictional force stops the block. What was the original compression distance of the spring?

(this question is from an algebra based physics class) A spring ( K= 100 N/n) is attached to a post on a table (h=0.9) high. It is compressed 5 cm and a mass (m1= 5kg) is placed next to the spring, and is released from rest. The friction between the mass and the table is negligible. It collides and sticks to a second mass (m2= 5kg) which is at rest at the end of the table. Both masses fly off...
