For the ball in the previous problems, we use I=0.4 m r2 . Pick 2 correct answers Group of answer choices Kinetic energy is 1/2m v2 (m the mass whatever it is and r is the radius) in each case Kinetic energy is 0.7 mv2 (m the mass whatever it is and r is the radius) in each case Velocity after d meters does not depend on mass and radius (only on d and angle)
