Steven is trying out for the position of pitcher on the baseball team. He can throw the baseball fast! The coach has clocked some of his pitches at 85 mph. Some of Steven's friends decided to play a joke on him and replaced one of the baseballs with one that they tampered with. Instead of a mass of 145 grams, the boys added a lead weight so the mass is now 200 grams.

The difference in the mass is not significant and will not affect the force needed to throw the ball 85 mph.
This statement is an inaccurate explanation. According to Newton's second law of motion, F = ma, the force required to accelerate an object is directly proportional to its mass. Therefore, if the mass of the baseball increases, Steven would need to apply a greater force to achieve the same speed of 85 mph.
