On a different planet, a ball is fired straight upwards from the ground with an initial speed of 100 m/s. At the same instant, a second ball is dropped from the top of a cliff 400 m above the ground. The balls arrive at the same vertical location at the EXACT instant that the ball thrown upwards reaches its highest point. Determine the magnitude of the acceleration due to gravity on this planet. In other words, find g on this planet. You can assume there is no air resistance.
