Question

Derivation of formula time of descent

Answer 1

Answer:

Ascent:

v=u−gt a

Or,

0=u−gt a

Or,

Time of ascent, t

a =u/g

Now, v 2 =u 2 −2gh Or,

u=2gh

or

t a = 2gh /g ---(1)

Descent:

v 2 =u 2 +2gh

here u=0

So, v= 2gh

Now applying v=u+gt

d and putting u=0,

we get v=gt d

So time of descent,t

d = gv = g2gh ---(2)

From (1) and (2) we get,

t a =t d
