Solve the all parts of given problem:
Problem: When a ball is dropped through a height, its potential energy changes. Suppose all this energy gets converted into internal energy of the ball once it has stopped bouncing and the specific heat of the ball is 0.850 J/g-K (no heat loss to the environment).
Part A: Calculate the height from which the ball must be dropped to increase its temperature by 1.00oC.
Part B: At what velocity must a 20.0 g object be moving to possess a kinetic energy of 1.00 J?
Please do a step by step solution since I'm kind of lost with this problem.
