500
This exists when all the forces acting on an object result in the object staying at rest or moving at a constant speed in the same direction.
What is balanced force?
500
Dolphins, marine mammals, like to porpoise in the water as air produces less resistance than water when traveling long distances. When the average bottlenose dolphin jumps back into the water, it hits the water with about 8,000N of force. The water, on average, hits back with this much force.
