Question

A projectile can have the same range \( R \) for two angles of projection. If \( t_1 \) and \( t_2 \) are the times of flight in two cases, then what is the product of two times of flight?

• A. \( t_1 t_2 \propto R \)
• B. \( t_1 t_2 \propto R^2 \)
• C. \( t_1 t_2 \propto R^3 \)
• D. \( t_1 t_2 \propto R^4 \)

Hint:

For projectiles with the same range, the product of the times of flight is proportional to the square of the range.

Answer 1
