A bullet with mass 5.06 g is fired horizontally into a 2.038-kg block attached to a horizontal spring. The spring has a constant 5.58 102 N/m and reaches a maximum compression of 5.89 cm.
(a) Find the initial speed of the bullet-block system. (m/s)
(b) Find the speed of the bullet. (m/s)

Equipotentials between two parallel lines with a floating circular electrode. I dont need to know the exact potentials, What is the potential of the circular electrode
What is the effective spring constant (that is, the ratio of force to change in length) of a copper cable that is 7.0 in diameter and 13 long?
A block of mass 12-kg slides from rest down a frictionless 34° incline and is stopped by a strong spring with k = 1.0x 10^4 N/m. The block slides 3 m from the point of release to the point where it comes to rest against the spring.
