Question 825784: please can you help mw with this question:
a ball is dropped from a tall building and falls from acceleration of magnitude
10ms-2. the distance between floors in the block is constant. the ball take 0.5s to fall from the 14th to the 13th floor and 0.3 s to fall from the 13th floor to the 13th. what is the distance between floors?
thankyou
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
= constant distance between floors, in meters

= acceleration of gravity
= downward velocity as the ball reaches the 14th floor, in m/s
Then, 0.5 seconds later, we have
= downward velocity as the ball reaches the 13th floor.
After another 0.3 seconds,
= downward velocity as the ball reaches the 12th floor.
In linear motion with constant acceleration, distance is the product of average speed and time.
Between the 14th and 13th floors:

Between the 13th and 12th floors:

We solve the system below any way we can
--> to find that the distance between floor is meters.

I would use a combination of equations:
