As a 1250kg car was passing through an intersection at 8.12m/s (0deg) it was hit broadside by a pickup truck running a red light at 8.25m/s (90deg). Immediately after the 0.185s collision, the velocity the the car was 5.65m/s (73.1deg), and the velocity of the truck was 64.7m/s (38.5deg). What is the mass of the truck? What is the percentage of kinetic energy lost in the inelastic collision? The answer to the second question is 44.2% but I get 44.13460052% ....am I wrong or is the answer wrong?
