Answer 1

Answer:

Let u be the velocity at M.

Since, M is the midpoint of AB .

So, AM = BM = s

By using formula :

v^2 - u^2 = 2as

for AB

u^2 - 7^2 = 2as

u^2 - 49 = 2as ...(I)

Similarly, for BM

289 - u^2 = 2as ...(II)

from equations (I) & (II) , we get

289 - u^2 = u^2 - 49

On solving, we get

u = 13 m/s
