Bonnie and Clyde are sliding 270 kg bank safe across the floor to their getaway car. The safe slides with a constant speed if Clyde pushes from behind with 395N of force while Bonnie pulls forward on a rope by N of force.
What is the safe's coefficient of kinetic friction on the bank floor?
Car 1 has a mass of m1 = 65000 kg and a velocity of v01 = +0.80 m/s. Car 2 has a mass of m2 = 92000 kg and a velocity of v02 = +1.2 m/s, overtakes car 1 and couples to it. Determine the velocity of their center of mass (a) before and (b) after the co..
