Al. Mass 1 (0.85 kg) moves horizontally with an initial velocity, vli = 25 m/s and collides with Mass 2 (2.8 kg) After the collision, Mass 1 moves at an angle o = 250 while Mass 2 moves at 0 = 420 V1i a) Set-up the equations for conservation of momentum in the x- and y- directions. Var b) Solve for the final velocities, vir and var. First, use the y-direction equation to find var in terms of vir . c) Next , substitute that into the x-direction equation to solve for vir. Once you have that, you can calculate v2f. d) Is energy conserved? Calculate the initial kinetic energy and the final kinetic energy in this system.|
