At location A, a 46.0-kg sledder has a height of 40.0 m above the bottom of the hill and a speed of 15.0 m/s. While coasting to location B at a height of 18.0 m, 1140
J of mechanical energy are dissipated. Another 1720 J of mechanical energy are
dissipated while moving from location B to C. Determine the missing potential
energy (PE) and kinetic energy (KE) values for locations A, B, and C and calculate
the speed at C. Use g = 9.8 N/kg.
