    A chemistry question on my test referring to the specific heat capacities of granite and limestone. Which would be more effective? Mass of both is the same, c for granite=0.45kJ/kg*K, c for limestone=0.11kJ/kg*K

    Cannon fires a cannonball 500.0m downrange set at 45.0 degree angle. What velocity

    does the ball leave at? When I use the famous five equation with no time variable, does the formula initial velocity account found in that formula account for the y-component or the initial velocity itself?
