I've got a question on projectile motion and don't know where to start. A dart player stands 3m from the wall on which the board hangs and throws a dart which leavs his hand with a horizontal velocity at a point 1.8m above the ground. The dart strikes the board at a point 1.5 m from the ground. Calculate a) The time of flight of the dart b) The initial speed of the dart c) The velocity of the dart when it hits the board. The problem is at a) and i think once i know a) i should have no problems doing the rest. Thanks alot.
