Question

A missile is fired for maximum range with initial velocity of 20m/s. If g=10 m/s , the range of the missile is??

Answer 1

Answer:

Range, R = 40 meters

Explanation:

It is given that,

Initial velocity of the missile, u = 20 m/s

The missile will acts as a projectile. The range of the missile is defined as the distance covered by the projectile. The mathematical formula is given by :

$R=\dfrac{u^2sin2\theta}{g}$

Here, $\theta=45^{\circ}$ (for maximum range the angle of projection is 45)

$R=\dfrac{(20)^2sin2(45)}{10}$

R = 40 meters

So, the range of the projectile is 40 meters. Hence, this is the required solution.
