As a baseball is being caught, its speed goes from 43 to 0 m/s in about 0.003 s. Its mass is 0.145 kg. (Take the direction the baseball is thrown to be positive.)
(a) What is the baseball's acceleration in m/s2? (Indicate the direction with the sign of your answer.)
(b) What is the baseball's acceleration in g's? (Indicate the direction with the sign of your answer.)
(c) What is the size of the force acting on it?
