Question 1
A child who weighs 30 kg is on a swing at a height of 2 meters. Calculate the potential energy of the child. If they swing down, what will their kinetic energy be at the lowest point?
💡 Hint: Use conservation of energy.
Question 2
A car with a mass of 900 kg is traveling at a velocity of 15 m/s. Calculate its kinetic energy. If this car hits a bump and rises, find the height it could reach while transforming all its kinetic energy into potential energy.
💡 Hint: Remember, energy conservation explains this transformation.
