1. The problem statement, all variables and given/known data Car 1: 2000 kg Car 2: 3000 kg coefficient of friction: 1.5 angle of movement: 40 degrees North of East displacement of vehicles: 6.0 m What was the friction force that acted upon the locked sliding cars to stop them? What was the magnitude of the acceleration that this force produced on the sliding cards sliding together? 2. Relevant equations Ff = coe of fric x mass x 9.81 3. The attempt at a solution so to figure out the friction force I did: (1.5)(2000 + 3000)(9.81) = 73575 N but I don't know how to figure out the magnitude of acceleration! would the formula be this? coe of fric x 9.81 ??? If that isnt the formula can someone please help me???
