Please show work symbolically:

Two 25 kg blobs are fired towards one another from opposite ends of a football field (distance = 100 m). They are fired at the same initial velocity of 50 m/s and at the same angle of 30 degrees from the horizontal field.

Immediately prior to their collision, what height are they at? What is their momentum in both x and y directions at collision? What is the kinetic energy of the new combined blob after collision? What is the max height of the combined blob after collision? What will its velocity be when it hits the ground?
