System of inertia .55kg consists of spring gun attached to a cart. System is at rest on horizontal track. A .05kg projectile is launched at an angle of 40 degrees. What speed does the cart recoil if the projectile rises 2.1m at its maximum height?

Using the law of conservation of momentum,
m1v1 = m2v2

I think your question is missing the time it takes to rise upto 2.1m or the velocity of the projectile.
