Answer:

(d) 40m

Explanation:

As we know that,

For maximum range of a projectile the angle is 45°.

Therefore,

R= u^2×sin(2×45)/g

or

20×20×sin90°/10

or

40m

Dear student,

Given :-

  • velocity = 20 m/s
  • g = 10 m/s
  • maximum range, ∅ = 45°

To find :-

  • The range of missile

Solution :-

We know for the horizontal range from the concept of projectile motion that;

R = u²sin(2∅)/g

Putting the given values in the above equation, we obtain;

R = (20)² sin 90° / 10

R = 400/ 10

R = 40 m

Hence, the range of the missile is 40 m.
