A .14 kg baseball moves toward home plate with a velocity vi=-36 m/s x. After striking the bat moves vertically upward with a velocity vf= 18 m/s y. (a) Find the direction and magnitude of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5ms. (b) How would your answer to part (a) change if the mass of the ball were doubled? (c) How would your answer to part (a) change if the mass of the bat were doubled?
how do u do this problem am so confused? This is what i came up with so far
((36)^2+(18)^2)^(1/2)= 40.2492
tan^-1(18/36)= 26.5651
i don't know what to do from there?
