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.) please give process

since the object is thrown horizontally

Vy=0

t=2s

Vx=20

applying equation in vertical direction

h=ut +1/2gt^2

h=1/2*9.8*4

=19.6m/s^2

thanks and regards
