Question

. Can you show me how to set up these problems. You dont have to compute them. I'm giving lots of points for this becuase it is multiple qeustions.

A common mistake that is often made in analyzing collisions is to assume that kinetic energy is always conserved. The following exercise is designed to highlight just how misleading this assumption can be in terms of predicting a system's behavior following a collision.

Answer 1

apply the law of conservation of momentum as mu = (m+M) V

V = 0.012* 300/(2+0.012)

V = 1.789 m/s

so

1. initial K E of the syystem   =     0.5 mv^2   + 0.5 MV^2

initial KE = (0.5*0.012 * 300*300) + (0.5 * 2 * `1.789 *1.789)

Iniitial KE = 543.2 Joules
