1.a baseball hits a home run, according to newton's laws of motion which of the following statements could be true in this scenario: statement 1: the bat pushes on the ball with the same force as the ball pushes on the bat. statement 2: newton's 2nd law explains why the ball travels farther than the bat. statement 3: the bat hit the ball causing the ball to change direction. this is an example of unbalanced force in newtons first law of motion. choose all statements that are true. 2. a bowling ball on earth weighs 11 pounds and has a mass of 5kg. the gravitational pull on the moon is 1/6 of the gravitational force on earth. what would the mass of the bowling ball be on the moon? 3.how much force would you need to use in order to accelerate an 80kg shopping cart to 0.2 m/s^2 (f=ma)?
