Question
A particle is projected vertically upwards from a point A on the ground. It takes t1 time to reach a point B but it still continues to move up. if it take further t2 time to reach the ground from point B then height of point B from the ground
Options
A.
g(t1 + t2)2
g(t1 + t2)2B.gt1t2
C.
g(t1 + t2)2
g(t1 + t2)2D.
gt1t2
gt1t2Solution
Lets take the top most point of trajectory be C.
Now, tAC = 
; And, tBC = 
∴ Since, AB = AC - BC ; And, tBC = =
=
