STANDARD Physics Time of Flight MCQ Question
A shell is fired from a fixed artillery gun with an initial speed u such that it hits the target on the ground at a distance R from it. If t₁ and t₂ are the values of the time taken by it to hit the target in two possible ways, the product t₁t₂ is
R/g
R/2g
R/4g
2R/g
Correct Answer
Detailed Explanation
The shell can hit the target at the same range for complementary angles. The product of the times of flight for these angles is given by 2R/g.
