Challenge Problems
Push your limits with advanced challenges
A rock of mass 3 kg is lifted to a height of 10 m. Calculate the potential energy gained. If the rock falls, how much kinetic energy will it have just before hitting the ground?
💡 Hint: Use the same height in both calculations.
A bicycle of mass 12 kg is moving at a speed of 8 m/s. Calculate its kinetic energy. If the biker abruptly stops, what happens to that kinetic energy?
💡 Hint: Remember to square the speed when calculating kinetic energy.
