Question
Two particle A & B projected along different directions from the same point P on the ground with the same velocity of 70 m/s in the same vertical plane. They the ground at the same point Q such that PQ = 480 m. Then : - (g = 9.8ms/s2]
Options
A.Ratio of their time of flight is 4 : 5
B.Ratio of their maximum height is 9 : 16
C.Ratio of their minimum speeds during speeds during flights is 4 : 3
D.The bisector of the angle between their directions of projection makes 45o with horizontal
Solution
Range =
⇒ 480 = 
× sin 2θ(90 - θ) projection angle has same range.
Time of flight :
T1 =
; T2 =
