Please answer question 6. thanks
1. A 7 kg lead sphere that has 35 °C temperature falls through the air. When the sphere is 15 m above the ground, its speed is 20 m/s. Suppose that when the sphere hits the ground, 75% of its kinetic energy converts to heat that raises its temperature. Specific heat capacity of lead c = 128 J/kg.°C, g=9.8 m/s. A. Setup with a labeled diagram. b. Write down in symbols the energy equation. c....
