t y g == = 22 4 5 303 ( . m) 9.8 m / s s. 2 Therefore, the speed of the boat is v b 12 40 m 3.03 s m/s . . 51. The speed of the boat is constant, given by v b = d / t . Here, d is the distance of the boat from the bridge when the key is dropped (12 m) and t is the time the key takes in falling. To calculate t , we put the origin of the coordinate system at the point where the key is
