A 5.00 gram bullet moving horizontally with a speed of 400 m/s collides with a wooden block. After moving 2.00 cm into the block the bullet stops moving. Was work done on the bullet? If so describe the type of work and the force that did the work.     a. yes, negative work, force is in the opposite direction as the initial velocity of the bullet   b. yes, positive work, force is in the same direction as the initial velocity of the bullet   c. yes, positive work, force is in the opposite direction as the initial velocity of the bullet   d. No work was done on the bullet   e. yes, negative work, force is in the same direction as the initial velocity of the bullet

Instantaneous Power

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.
