As shown below, a 840 kg car traveling east collideswith a 1730 kg pickup truck that is traveling north. The twovehicles stick together as a result of the collision. After thecollision, the wreckage is sliding at vf = 19 m/s in thedirection θ = 25° east of north. Calculate the speed ofeach vehicle before the collision. The collision occurs during aheavy rainstorm so you can ignore friction forces between thevehicles and the wet road. Express your answers usingapropriate mks units.
A.) vcar,i =
B.) vtruck,i =
C.) Determine what fraction of the total initial KE isturned into thermal energy as a result of thecollision.
