Ijust pulled up to sheetz and filled my car up with gas. explain the transfer of energy that would occur once i start then drive my car--consider the type of energy that exists within the gas molecules, explain the transfer of form of energy as gas is burned and i drive my car, and consider how the engine and tires may feel after i have traveled in my car. (use the following terms in your explanation: potential energy, kinetic energy, friction, and heat.)

Suppose you use a machine that gives you a mechanical advantage of 2 to achieve an output force of 30newtons what must the input force be

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
