An underwater inspection vehicle moves east at constant velocity while remaining at the same depth. It is attached by a taut cable to a support vessel above and to the west.
The table shows the other forces acting on the vehicle.
| Force | Magnitude | Direction |
|---|---|---|
| driving force | 480 N | east |
| drag | 350 N | west |
| weight | 620 N | downwards |
| upthrust | 500 N | upwards |
Calculate the horizontal component and the vertical component of the tension in the cable. Give the direction of each component.
The cable breaks.
Explain the direction in which the vehicle initially accelerates.
