How Does Force Affect Javelin Momentum and Speed?

[almost__overnow]

A 75kg javelin thrower applies a 300 N force to a 2.0kg javelin for 1.5 seconds.

a)what is the increase in momentum of the javelin?

b)what is the speed of the javelin immediately after the throw?

all i know is that ft = /\(mv) /\ is suppose to be a triangle.

Look up the relation between change in momentum and impulse.

Hint: the initial momentum is zero
