An object is thrown horizontally from the open window of a building. If the initial speed of the object is 20 m/s and it hits the ground 2.0 s later, from what height was it thrown? (Neglect air resistance and assume the ground is level.)

An object is thrown horizontally from the open window of a building. If the initial speed of the object is 20 m/s and it hits the ground 2.0 s later, from what height was it thrown? (Neglect air resistance and assume the ground is level.) Initial vertical velocity = 0 formula: s = ut + (1/2)*g*t^2 s = 0 + 1/2*9.8*2^2 s = 9.8*2 = 19.6 m
