A 6.0-kg bowling ball (I=2 M r^2 / 5) starts from rest and rolls, without sliding, down a gradua

Name: A 6.0-kg bowling ball (I=2 M r^2 / 5) starts from rest and rolls, without sliding, down a gradual slope until it reaches a point 80 cm lower than its starting point. How fast is it then moving? Ignore friction losses. Do you actually need the mass? [Hint: Why were you not given r ?]
