A golf ball is hit into the air, but not straight up, and encounters no significant air resistance.
Which statements accurately describe its motion while it is in the air?
A.On the way up it is accelerating upward, and on the way down it is accelerating downward.
B.On the way up, both its horizontal and vertical velocity components are decreasing; on the way down, they are both increasing.
C.Its vertical acceleration is zero at the highest point.
D.Its horizontal velocity does not change once it is in the air, but its vertical velocity does change.
I hope you can see that on the way up it's decelerating and on the way down it's accelerating. Therefore there should be some point where the acceleration is stationary or 0.
A. How can it accelerate going against gravity?
B. How can the horizontal component be decreasing?
C. What do you think?
D. The horizontal component should be constant if air resistance is ignored. I'll let you finish examining this answer.
Please post some work. I don't see how you're helped just by copying and pasting here.
