    Solving Car Crash Scenario: Find v1 of Car A

    Ah - so I need the force on Car A to find the Work done by Car A, so that I can substitute it into KE=½mv² and get v3.

    Solving Car Crash Scenario: Find v1 of Car A

    Thanks so much for your help everyone - I'm in over my head at the moment! To answer some questions: I think the force on Car A would be -6844N BvU - The speed after the collision and the stop of car A is assuming that the only resistance is rolling resistance, so brakes are no longer being...

    Solving Car Crash Scenario: Find v1 of Car A

    Homework Statement Car A (m1=1405kg) crashes into Car B (m2=873kg) which is stationary and perpendicular to Car A. Car B is moved a distance of 1.8m out of the way and Car A rolls to a stop 9.6m away at 1.93 m/s. Assuming the coefficient of friction is 0.8, can the velocity of Car A be...
