1) A racing car has a mass of 1525 kg. What is its kinetic energy if it has a speed of 35 m/s?
2) How much potential energy does Tim,with mass 60.0 kg, gain when he climbs a gymnasium rope a distance of 3.5 m?
Physics 11th grade -
KE = 1/2 m v^2
PE = mgh g = 9.8 m/s^2
Just substitute your values directly.
