A spear of mass m is propelled horizontally from a spear gun by a scuba driver. The initial speed of the spear is V. The force that resists its motion through the water is given by FD = kV2, where k is a constant. The spear is effective against sharks when its speed is above V1. The effective range of the spear is given by (A) om) In m V. V (B) In (C) (D) None of the above
