Answer: The ranges r1 and r2 are equal.
Explanation: In the first case, the angle at which the projectile was thrown was 30 degrees. In the next case, it is 60 degrees. So, we can clearly see that the angles are complementary. Hence, as we know that when the angles of projection are complementary, then the ranges are equal .So, we can conclude, r1=r2.
