How much time (as a fraction of the period t) does it required for a wave’s crest (maximum) to reach the position where the trough (minimum) was at t = 0?

Explanation:

From the billow figure the wave required T time to complete the length

Now from the figure it is clear that the length between the maximum crest and minimum crest is

As the distance is decreases by 4 times so the time will alos decreases by 4 times

So the required time for a wave to reach from maximum crest to minimum crest is

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
