The answer to this is false, I hope that helped
Answer:
0.16 kgm/s
Explanation:
= Mass of pellet = 2 g
= Mass of golf ball = 45 g
= Initial Velocity of pellet = 60 m/s
= Initial Velocity of golf ball = 0 m/s
= Final Velocity of pellet = 40 m/s
= Final Velocity of golf ball
In this system the linear momentum is conserved

As the golf ball is being shot 4 times every second the momentum delivered to the golf ball each second is 
D. B and C only
My sister just took the test and im sitting next to her and D is the correct answer
The speed will increase, as there is acceleration, while the acceleration will remain constant, as gravity is constant.
