A trayson crystal torpedo, traveling at 2.40 x 10^6 m/s, is lanuched against the Zargon B-Class Warship. The Trayson Torpedo has a mass of 126 kg, and a diameter of 30.0 cm. The Zargon Warship uses its laser puslar to stop the torpedo in its tracks. The laser puslar has an intensity of 6.50 x 10^20 W/m^2. Half of the energy of the pusler is absorbed by the torpedo, and hald is refelcted back. How long(in time) must the pusle be to stop the torpedo?
