Calculating Impulse for a Leaping Cricket: A Physics Problem

[sealedhuman77]

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?

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.
