This is a projectile motion question. Assume the acceleration due to gravity is g = 9.81 m/s2. What is the magnitude of the vertical displacement in metres if the initial velocity has a magnitude of 23.6 metres/second at an angle of 41.3 degrees below the horizon and the time of flight is 1.8 seconds. I want the size here, not the size and the direction. I have already given you the direction in the question.
