Average force on a batted ball

A baseball of mass $0.15\mathrm{kg}$ reaches the bat horizontally with speed $35m/s$ and is hit back along the same direction, in the opposite sense, at $45m/s$. The contact lasts $1.5\mathrm{ms}$. Compute the magnitude of the impulse received by the ball and the average force exerted by the bat, neglecting the weight during the contact.
