Batter hits a ball momentum problem

A batter hits a ball with a force of F(t)=(13000N)sin(1.05ms^-1) for 3.00ms. A baseball is thrown so it has a velocity of 35.0m/s toward the batter just before it hits the bat. Assuming the baseball has a mass of 300.0g calculate:

a. the impulse delivered to the ball over the 3.00ms

b.the velocity of the baseball just after it leaves the bat

I really don't know where to start. The answers are impulse=24.8N and 47.5m/s

Any help would be great!

I'd start with the equations, and identifying what type of collision it is. Would you call this collision elastic, inelastic, or perfectly inelastic?

i would say its elastic, what equations are you talking about?

F(t)=(13000N)sin(1.05ms^-1)
i don't understand. sin is a function for angles, how can you deduce "sin 1.05ms-1"

impulse=24.8N
impulse is basically change in momentum. so the unit is kg ms-1 not N

m1v1=m2v2

impulse=F*change in time
