Four ball are simultaneously launched with the same speed from the same height and h above the ground. At the same instant, ball 5 is released from the rest at the same height. Rank in order, from shortest to longest, the amount of time it takes each of these balls to hit the ground ( some maybe simultaneously.)

The ball 1 will take longest time to hit the ground  while ball 4 will take shortest time as per the ranking,

Ball 4 < Ball 3 <  Ball 2 = Ball 5 < Ball 1

Given data:

Four balls are simultaneously launched with the same speed from the same height and h above the ground.

And at the same instant, the ball 5 is released from the rest at the same height.

From the given picture and considering all the logical aspects, we need to consider the y component of initial velocity of each ball.  

So, the ranking will be in the order from the least to long as,

Ball 4 < Ball 3 <  Ball 2 = Ball 5 < Ball 1

Thus, we can conclude that the ball 1 will take longest time to hit the ground  while ball 4 will take shortest time as per the ranking,

Ball 4 < Ball 3 <  Ball 2 = Ball 5 < Ball 1

4, 3, 2 & 5, 1

Explanation:

Look at the y component of each initial velocity.  Ball 2 and 5 both have v₀ᵧ = 0, so they land at the same time.  Ball 4 has the highest downwards velocity, so it will land first.  Logically, Ball 3 will land after 4 and before 2 and 5.  Ball 1 will take the longest to land.

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
