Question Column Three objects are being thrown up in the air with same amount of force. Lauren states that the tennis ball will go highest. John thinks the soccer ball will go the highest. Whose thinking is correct? Prove it. ObjectWeight Basketball ball400 grams Soccer ball300 grams Tennis ball100 grams

Answer Column Lauren is correct. The lighter the object (less gravitational pull) the farther it travels when the same force is applied. The tennis ball was 100 grams which is the lightest of the three balls.
