a) An 18.0 kg curling stone is released with a spped of 4.0 m/s. what is its kinetic energy upon release?
b) Determine the amount of thermal energy produced when an 18.0 kg curling stone that is released with a speed of 4.0 m/s slides to a stop over a distance of 30.0 m due to a 4.80 N force of kinetic friction.
c) What is the difference between (a) and (b) Explain?
d) Given that the curling stone is moving and then comes to a stop, does this mean energy is lost? Explain.
