ive tried this question all day, and its due tonight. here it is

The force exerted on a 0.145 kg baseball by a bat changes from 0.0 N to 1.0 104 N over 0.0010 s, then drops back to zero in the same amount of time. The baseball was going toward the bat at 23 m/s.

(a) Draw a graph of force versus time. (Do this on paper. Your instructor may ask you to turn in this graph.) What is the average force exerted on the ball by the bat?

________ N

(b) What is the acceleration of the ball?

____________ m/s2

(c) What is the final velocity of the ball, assuming that it reverses direction?

__________m/s

i already used up all my chances for part b, so that one is useless.

i tried finding acceleration using a= change in velocity over time,

but that didnt work. i tried finding the force also, but i kept getting the same answers (3335,2300,11500,-11500,72500.)

i understand the subject, i just cant find the answer. thanks
