3-2.Motion in Plane
medium
Two projectiles $A$ and $B$ are thrown with the same speed such that $A$ makes angle $\theta$ with the horizontal and $B$ makes angle $\theta$ with the vertical, then
A
Both must have same time of flight
B
Both must achieve same maximum height
C
Amust have more horizontal range than $B$
D
Both may have same time of flight
Solution
Depending on the value of $\theta$ one can have same or different time of flight, range o maximum height. Therefore must statement is wrong. They may be equal or may not be. This is only possible for $\theta=45^{\circ}$
