Two projectiles are fired from the same point with the same speed at angles of projection 60° and 30° respectively. Which one of the following is true?

1. Their maximum height will be same
2. Their range will be same
3. Their landing velocity will be same
4. Their time of flight will be same

Correct answer: Their range will be same

Solution

For projectiles launched with the same speed, the range is the same if the angles of projection are complementary (i.e., their sum is 90°). Here, 60° and 30° are complementary angles, so their ranges will be the same.
