The torpedo with a speed of60.0 m/s relative to the submarine. How for east or west of the ship should the sub be when it fires submarine moving east at 3.0 m/s sees an enemy ship 100 m north of its path. The sub els torpedo tube happens to be stuck in o position pointing 45" west of north The tube free a torpedo with a speed of 600 west of the Rhip should the sub be when it fies? north of path. The submarine's torpedo tube happeng to be stuck in a position pointine 450 weetornorth The tube submarine moving east at 30 enemy ship 100 torpedo with a speed of 60 m/srelative to the submarine. How for east west of the ship should the be when it fires? submarine moving east at 30.0 m/s sees an enemy ship 100 m north of its path. The submarine's torpedo tube happens to be stuck in a position pointing 45 west of north. The tube fires a torpedo with a speed of 6.0 m/srelative tothe Rubmarine. How far east or Rt of the ship should the Rub be when it fres? Up Correct Part B Finish the solution of the problem. Suppose that the positive dreoton is to the east.

B. 100 = vy*t ; x = vx*t
The topedo must travel 100m North in same time it travel x in west
vx = -6*cos(45) +3, vy = 6sin(45)
x/100 = vx/vy = (-6*cos(45) +3 ) /6sin(45)
= -1 + 0.5* 1.414 = -0.293 m
x= -29.3 m
the ship must be located +29.3 m East when firing
