Hi, I don't seem to be getting the right answer for this question. Essentially, you have a dart that's shot at a board 3 metres away from it at 21ms-1. The point of projection is in line with the bullseye. I've calculated that the dart lands 0.1 metres below the bullseye. But, my calculation for the angle that the dart makes with the horizontal the moment it hits the board seems to be wrong. I do tan-1(0.1/3) to get the angle, which is 1.909... But that answer is wrong, the right answer is 3.81 degrees below horizontal. I'd appreciate any help.
