Question

plzz solve it from kinematics

Answer 1

We know that a certain height is reached two times in a vertical projection.(One while going upward,one while going back downward)

let the height reached in time t be h

maximum height=H

difference in height=H-h

now H is reached in T and h is reached in t time.

So H-h is reached in (T-t) time ...(1)

while going back down H-h is reached in (T-t)seconds

So,

H-h=u(T-t) + ½g(T-t)2

but u =0 (velocity at max height is zero)

So,

H-h = ½g(T-t)2

h = H – ½g(T-t)2 or H-½g(t-T)

HOPE IT HELP...

Hey mate here is the correct answer....

now H is reached in T and h is reached in t time.

but u =0 (velocity at max height is zero)

So,

h = H – ½g(T-t)2 or H-½g(t-T)
