Projectile Motion- What is the relationship between the following?

Question

surry99 · Answer

ok, have you studied projectile motion yet in class?

anonymous · Answer

Yes, it follows a parabolic motion

surry99 · Answer

ok and what do you know in general about the horizontal and vertical motion?

surry99 · Answer

That is, in a projectile motion problem can you solve them separately?

surry99 · Answer

No....think about it again.

surry99 · Answer

Yes, that is true.

surry99 · Answer

b) What about vertical displacement and time?
I will give you a hint...if the object starts and finishes at the same height and the total time of flight is t seconds, at what fraction of t will the object be at its maximum height?

surry99 · Answer

still there?

surry99 · Answer

no problem...draw a symmetrical parabola and ask yourself if it takes t seconds to travel the distance x, where does the maximum height occur

surry99 · Answer

|dw:1417413356324:dw|

surry99 · Answer

which is when time is t/2...agreed?

surry99 · Answer

The maximum vertical height for this graph would occur when time equals t/2
assuming that t is the total time of flight.|dw:1417413836726:dw|
