Answer:
At point A, the cart has high potential energy. At point b, the cart is pulled down by gravity. At point c, the cart gains its highest kinetic energy. At point d, the cart returns back to the same state but with lower potential energy.
Answer:
dry ice, air fresheners, polar evaporation, arsenic treatment
This question is probably referring to heat energy transferring from the car to its surroundings.
When water changes to ice, its density decreases and its volume increases.
Speed is the same as the initial: 25m/s.
*if* you need vectors though:
final velocity = (25*cos(35), -25*sin(35) ) m/s
