- Give an example of each type of kinetic energy.During a hiking trip, Bob went 600 m up in 1 hour. How much work did Bob do against gravity if his mass is 92 kg? select one 541 kJ 441 kJ 341 kJ 641 kJA 24 kg child starts from rest and slides down a slide 4.3 m high. At the bottom of the slide is moving 2.32 m/s? How much work in joules was down by the nonconservative force of friction on the child
- Why is kinetic energy a form of energy associated with an object's motion?A 2 gram coin is which is initially at rest is dropped from the observation deck of a skyscraper 400 meters above the street below. What is the work done by gravity on the coin as it falls? Joules Submit Answer Tries 0/3 Because there is air resistance the coin was slowed and hit the ground with a final velocity of 70 m/s. What is the kinetic energy of the coin at this speed? ? Joules Submit Answer Tries 0/3 How much work was lost to air resistance as the coin fell? Joules Submit Answer Tries 0/3 What is the average force exerted on the coin due to the air resistance as it fell?
