A crate is pushed across a level floor by a constant forcein the direction of motion. The force does 5 J of work on the crate. The kinetic energy of the crate increased by 3 J while the force was being applied.
i. How much work did gravity do on the crate while theforce was being applied?ii. How much work did friction do on the crate whilethe force was being applied?
A 20 kg crate is pushed across the floor at a constant velocity of 4 m/s with a force of 100 N. How much energy is lost to heat in the first ten seconds
