Solving Two dimensional motion Question A particle starts from origin at t = 0 with a velocity and moves in x-y plane under action of a force which produces a constant acceleration of Answers Option 1 It's initial velocity in Y direction is 5 m/s Option 2 Its initial acceleration in Y direction is 2.0 m/s2 Option 3 Resultant acceleration is 5 m/s2 Option 4 Body moves a horizontal distance of 84 m at a time 6 seconds Option 5 Vertical displacement at t = 5 seconds is 36 m Option 6 Resultant speed at 6s is 26 m/s Feedback No vertical initial velocity Use Pythagorian principle to find resultant velocity Horizontal displacement y(t) = 0 + 1.0 t2 Solution Incorrect Correct Incorrect Correct Incorrect Correct
