A hockey puck slides off the edge of a table at point A with an initial velocity of 20.0 m/s and experiences no air resistance
The height of the tabletop above the ground is 2.00 m. (a) What is the speed (not the velocity) of the puck just before it touches the ground? (b) What is the distance between point A and the point where the puck hits the ground?
Suppose an automobile's fuel could be made to burn hotter without harming the engine's operation. Would you still get the same amount of useful work from each gallon of gasoline?
A) It wouldn't make any difference, because the efficiency is related only to the amount of input energy, and not to the temperature of this energy. B) You would get more work, because heat engines are more efficient at converting chemical energy into thermal energy when the temperature is higher. C) You would get more work, because heat engines are more efficient at converting thermal energy into work when the input temperature is higher. D) You would get less work, because heat engines run less efficiently when the input temperature is higher. E) You would get less work, because less chemical energy would be used at the higher temperature.
