1850 kg car is set in mottion on a level road by a spring constant k=2.40x10^6 N/m that has been compressed 1.50m. the car leaves the spring as it passes point A and the driver slams on the brakes at pont B. The wheels lock and the car skids to a stop at point C, due to kinetic friction with coefficient uk=0.7
A. what is the intial mechanical energy of the system, with the spring compressed 1.5 m, before the car is released?
B. what speed will the car have when it leaves the spring at point A?
C. over what distance (BC) will the car skid to a stop after the brakes are applied and the wheels lock?
