Speed of the Enemy sub .....> <span> 25.0 km/hr which is (25/3.6) m/s = 6.94 m/s
We use the expression Speed = Distance/ time to find the distance
D = Speed*Time = 6.94 m/s * 3.5 = 24.305 m
The enemy sub will be 24.305 m closer </span>
If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
