Question

at the intersection of Ponce de Leon avenue and Eleanor Roosevelt avenue, a yellow subcompact car with mass 950 kg traveling east on Eleanor roosevelt colides with a red pickup truc with mas 1900 kg that is traveling north on Ponce de Leon and ran a red light. The 2 vehicles stick together as a result of the collision, and the wreckage slides at 16.0 meters per seconds in the direction 24.0 degrees east of north. Calculate the speed of each vehicle before the collision. the collision occurs during a heavy rain . u can ignore friction forces betweeen the vehicles and the wet road.

Explanation / Answer

north momentum is conserved: .          1900 * speedof van = (950 + 1900) * 16.0 cos24 .    speed ofvan =    21.93 m/s . east momentum is conserved: .          950 * speedof car= (950 + 1900) * 16.0 sin24 .    speed ofcar =    19.52 m/s east momentum is conserved: .          950 * speedof car= (950 + 1900) * 16.0 sin24 .    speed ofcar =    19.52 m/s
