Your physical therapist throws a baseball to you at a certain speed and you catch it. To increase the difficulty, the therapist is going to throw you a medicine ball whose mass is ten times the mass of the baseball. You are given the following choices. Rank these from easiest to hardest to catch.
1. The medicine ball thrown at the same speed as the baseball
2. The medicine ball thrown with the same momentum as the baseball.
3. The medicine ball thrown with the same kinetic energy as the baseball.
