A spring of constant 5 N/m is hanging from the ceiling. What size mass must be hung on it in order for its potential energy to equal 37 joules?

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

In a system, when potential energy decreases, then entropy also decreases. true false
