need help know ball 2 with a mass of 30 kg, is moving to the left at 10m/s. with what velocity should ball 1, with a mass of 10kg, move to the right and collide with 2, so that ball 1 rebounds with a velocity of 30m/s and ball 2 with velocity of 10m/s after the collision? assume the collision to be perfectly elastic

You should have a set of formulas for elastic collisions you can plug into. See attachment, where \(v_1\), and \(v_2\) are the final velocities, and \(u_1\) and \(u_2\) are the initial velocities.
