forces acting on the submarine are:
upward force =16160 N
downward resistive force=1130 N
downward weight=1500*9.8=14700 N
net force is along upward direction
net force magnitude=16160-1130-14700=330 N
then acceleration=net force/mass
=330/1500=0.22 m/s^2

When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 964 N and the drag force has a magnitude of 1022 N. The mass of the sky diver is 98.4 kg. Take upward to be the positive direction. What is his acceleration, including sign?
An empty bottle of mass 3 kg is released from a submarine and rises with an acceleration of 0.7 ms? . If the water causes a resistance of 0.5 N, the size of the buoyancy force causing the bottle to rise is

When a parachute opens, the air exerts a large drag force on it.This upward force is initially greater than the weight of the skydiver and, thus, slows him down. Suppose the weight of the skydiver is 915 N and the drag force has a magnitude of 1027 N. Themass of the sky diver is 93.4 kg. What are the magnitude anddirection of his acceleration?

Starting from rest, a 1.9x10-4 kg flea springs straight upward. While the flea is pushing off from the ground, the ground exerts an average upward force of 0.36 N on it. This force does 2.0x10-4 J of work on the flea. (a) What is the flea's speed when it leaves the ground? (b) How far upward does the flea move while it is pushing off? Ignore both air resistance and the flea's weight.

Starting from rest, a 1.8x10-4 kg flea springs straight upward. While the flea is pushing off from the ground, the ground exerts an average upward force of 0.41 N on it. This force does 3.6x10-4 J of work on the flea. (a) What is the flea's speed when it leaves the ground? (b) How far upward does the flea move while it is pushing off? Ignore both air resistance and the flea's weight.
