Acrobat Art of mass m stands on the left end of a seesaw. Acrobat Bart of mass M jumps from a height h onto the right end of the seesaw, thus propelling Art into the air.

Art’s mass is 40 kg, Bart’s mass is 70 kg, and the height of Bart’s initial jump is 4 meters.

A] How high is Art propelled?
B] How fast is Art moving just before he lands?
