Question

a projectile is thrown at an angle of 30 degree with the horizontal so that its range is 200m . another projectile is thrown at an angle of 60 degree with the vertical. calculate its range.

Answer 1

The answer is very easy. You don't have to do any calculation.

You are given that range of projectile with angle 30° is 200m. And you have to find the range of projectile with same initial speed at an angle of 60°.

We know that projectiles with angle x° and (90-x)° have same range.
Since 60° = (90 - 30)°, both will have same range.

So range is 200m.

Answer 2

Answer:

Hey,

The answer of ur question is:

200m

Explanation:

The sum of angle which make complementry angle has same range...

Ex: 45 + 45 = 90

30 + 60 = 90

etc...

Hope u will get help from this...

Have a nice day..✌✌✌
