Answer 2

Answer:

Time of flight, T = 2.04 seconds

Explanation:

Given that,

Speed of the object, v = 20 m/s

Angle with the horizontal, $\theta=30^{\circ}$

The time of flight of a projectile is given by :

$T=\dfrac{2v\ sin\theta}{g}$

g is the acceleration due to gravity

$T=\dfrac{2(20)\ sin(30)}{9.8}$

T = 2.04 seconds

So, the time of flight on an object is 2.04 seconds. Hence, this is the required solution.
