In which situation would the momentum of a moving object increase?

Question

A. A force acting in the direction of the objects motion is removed from the object.
B. A new force acts on the object, opposing the objects motion
C. A force acting in the direction opposite the objects motion is removed from the object
D. Two forces of equal magnitude act on the object in opposite directions

Answer 1

C. A force acting in the direction opposite the object's motion is removed from the object.

Answer 2

Steven is trying out for the position of pitcher on the baseball team. He can throw the baseball fast! The coach has cloaked some of his pitches at 85 mph. Some of Steven's friends decided to play 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. Steven winds up and throws.

All of the statements describe the possible results of this scenario except one. Which statement is an inaccurate explanation?

A. Since force equals mass times acceleration, Steven's throwing force must increase to throw the ball 85 mph
B. If Steven's throwing force is constant and the balls mass increases, the rate of acceleration will be less.
C. The difference in the mass is not significant and will not affect the force needed to throw the ball 85 mph.
D. Steven must throw the new ball with more force in order for it to achieve the same speed as previous throws

Answer 3

C. The difference in the mass is not significant and will not affect the force needed to throw the ball 85 mph.
