Passage / Comprehension

Two projectiles following the same trajectory are found to be 8 m apart at the same horizontal level 2 s after the second was projected. If both projectiles were projected with the same initial horizontal velocity of 4 m/s from the same point.

What will be the range of the path

Options:

Answer:

Solution:

$T_{O A} = T_{C D} = 2 s$

$T_{A B} = T_{BC} = \frac{T _{A C}}{2} = \frac{8/4}{2} = 1 s$

The total time of flight is $T = 2 + 1 + 1 + 2 = 6 s$ .

The horizontal range is $\frac{2 u _{x} u _{y}}{g} = \frac{2 ( 4 ) ( 30 )}{10} = 24 m$ .
