Two identical steel balls, each of mass 4.40 kg, are
suspended from strings of length 25.0 cm so that they touch
when in their equilibrium position. We pull one of the balls
back until its string makes an angle θ = 70.0◦ with the vertical
and let it go. It collides elastically with the other ball. How
high will the other ball rise?

You appear to be in college. By this time you should know the difference between the name of your school (Prince George's Community College?) and your subject (physics?).
since energy is conserved, and the balls are identical, the 2nd ball will rise just as high as the first ball was.
Be prepared for the next step, where the balls are not identical in mass!
