a baseball has a mass of 0.145kg. the ball is crossing the plate horizontally at 40 m/s when the batter hits the ball. The final velocity of the ball is 50 m/s stright up. what is the impulse that the batter gives the ball?

The magnitude of the velocity change is V = sqrt(40^2 + 50^2)= ___
The impulse is M*V = ___ kg m/s
