Question

At what angle an athlete should throw his javeline to attain the maximum range.

• A. ${60}^o$
• B. ${40}^o$
• C. ${30}^o$
• D. Range has nothing to do with the angle of projection

Answer 1

The correct option is B ${40}^o$

To attain the maximum range, projectile angle must be ${45}^0$ (without air resistance) and less than ${45}^0$ i.e. $\simeq {40}^0$ (with air resistance).
