Challenge Problems
Push your limits with challenges.
Question 1
A 1500 kg car is at rest at the top of a hill that is 20 meters high. Calculate its potential energy. Then if it rolls down the hill and reaches a speed of 25 m/s at the bottom, calculate its kinetic energy.
💡 Hint: Use the formulas for both potential and kinetic energy.
Question 2
A water balloon is thrown from a height of 5m. If it has a mass of 0.5 kg, calculate its potential energy before being thrown. What will be its kinetic energy just before it hits the ground?
💡 Hint: Consider that energy is conserved through the fall.
