A ball is dropped on a floor from a height of 2.0m. After the collision it rises upto a height of 1.5m. Assume that 40% of the mechanical energy lost goes as thermal energy into the ball.
Calculate the rise in the temperature of the ball.
Heat Capacity of the ball is 800JK-1

Δθ = 2.5x10-3
- Aditya Agarwal yeah. but how? how did you eliminate m? since heat capacity of the ball is given?
- Shaswata Roy If this is the right answer then I'm pretty sure there is some mistake in the question.I assumed that by heat capacity you meant specific heat capacity.
