A cannon fires a cannonball from ground level with an initial velocity of 25.0 m/s at an angle of 30.0° (Assume the cannonball lands at the same level from which it is fired.)

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.
