A particle is projected from a height of 0m above the ground, with initial velocity i + 4j. Find the time it takes for the particle to be travelling perpendicular to its original projection 6. A particle is projected horizontally with speed 40m/s from a point A. It hits the ground 00m horizontally from A. Find the height of A 7. A field 00m in length has two barriers of height m at a distance of 5m from both ends. A ball is kicked with speed 5m/s.
