Question

A missile is fired for maximum range with an initial velocity of 20 m/s. If g = 10 m/s^2, the range of the missile is

Answer 1

Answer

40 m

Explanation

If missile want to cover maximum range, the angle of projection must be

∡ = 45°

We will use Projectile Motion Formula (trajectory formula) articulated as

Maximum Range = Vo²sin2∡ / g

Where, the initial Velocity is Vo ,

the component along the y-axis is sin θ,

g is the acceleration

= (20)² sin ( 2 x 45°) / 10

= 400 * sin ( 2 x 45°) / 10

= 400 * sin ( 90°) / 10

= 400 * 1 / 10

= 40 m.

Answer 2

Answer:

. So, the range of the projectile is 40 meters.
