Cart and a projectile

Assignment Help Physics
Reference no: EM131705423

A system of inertia 0.55 kg consists of a spring gun attached to a cart and a projectile. The system is at rest on a horizontal low-friction track. A 0.050-kg projectile is loaded into the gun, then launched at an angle of 40 degrees with respect to the horizontal plane. With what speed does the cart recoil if the projectile rises 2.5 m at its maximum height?
