In a crash test, a 1.78x103 kg car is driven into a very sturdy wall at 48.1 m/s. If the wall recorded an average force of 3.82x10 N during the collision, then for this test Answers: a) What was the car's initial forward momentum? [kg-m/s] +8.56x104 b) What was the car's final forward momentum? [kg-m/s] 0.00 c) What was the impulse vector on the car? [N-s] -8.56x10* d) What was the duration of the crash? [s] 0.224 e) What was the car's average forward acceleration? [m/s?] -215
