Question

a body is moving vertically downward from A, the top of the tower reaches the ground in T1 second. If it is projected upwards with same velocity it reaches the ground in T2 second. at what time it will reach the ground , if it is dropped from A.

Answer 1

Answer:

Explanation:

a body is projected vertically downwards from A,

h = ut1 + 0.5gt1^2 ….............................(1)

it is projected upwards with same velocity

h = ut2 – 0.5gt2^2........................(2)

time it will reach the ground if it is dropped from A

h = 0 + 0.5gt^2..............................(3)

solve the three eqns. and get t in terms of t1 and t2.
