Cricket bat impulse problem

1. Homework Statement
A 20 g cricket (Acheta domestica) leaps through a 2.2 m horizontal distance. The initial velocity of the cricket makes a 28° angle with the horizontal direction. If it takes the cricket 0.010 s to leave the ground, what is the magnitude of the impulse of the total force on the cricket that gives it the speed needed for the jump?


2. Homework Equations
I = F[tex]\Delta[/tex]t = [tex]\Delta[/tex]p
Motion formulas


3. The Attempt at a Solution
Did not know how to approach problem

THanks

First solve the projectile motion problem: How fast must the cricket leap at the given angle to reach 2.2m?

Then you can worry about the needed impulse.
 
Thanks I got it now.
