This is a question from TBR translational motion Phase II
If all 4 objects were launched from a cannon mounted at a 45 degree angle what would be observed?
I. Object I would have the greatest range
II. Object IV would have the lowest velocity upon impact of the ground
III. The object experiences a greater displacement in the x direction in the first half of the flight than the second half of the flight
Given in the passage:
- Time of flight
I: 2.13s, II 2.14s, III 3.87s , IV 2.21s
- Wind resistance is proportional to velocity when the wind resistance is strong enough it can negate any acceleration and result in constant velocity
Answer is I and III
I understand why I is correct and II is incorrect but III seems strange to me. TBR says " Because of wind resistance opposing the direction of velocity it is constantly slowing the object down during its flight. this means that the object has greatest x direction velocity initially but that value is decreasing with time"
This statement is a bit confusing does it mean that the wind resistance is slowing it down more and more and making it displace less and why would that be the case?
Thanks!
