Calorimetry Problem: How to find the percentage of the initial mechanical energy absorbed as thermal energy by the aluminum sphere?

Problem: In a lunar experiment, a 950-g aluminum (920 J/ kg °C) sphere is dropped from the space probe while is 75 m above the Lunar ground. If the sphere’s temperature increased by 0.11 °C when it hits the ground, what percentage of the initial mechanical energy was absorbed as thermal energy by the aluminum sphere? Looking for step by step solution.
