RESPOND QUICK 30 MINUTES LEFT!!! In the diagram below, an engineer uses a single car to test a roller coaster track. Assuming that friction can be ignored and that the speed at A is
0(m)/(s)
. Where is the kinetic energy the greatest?In the diagram below, an engineer uses a single car to test a roller coaster track. Assuming that friction can be ignored and that the speed at A is 0 m/s. Where is the kinetic energy the greatest?
