a pitches takes 0.10 seconds to throw a baseball, which leaves his hand at a velocity of 30m/s. the balls acceleration is?

acceleration = (final velocity minus initial velocity)/time taken.
the formula is based on newton's 2nd law, which states that the rate of change of momentum of an object is directly proportional to the resultant force acting on it.
F = m(vu)/t
ma = m(vu)/t
hence, a=(vu)/t 
a = (300)/0.10
