The discussion centers on calculating the force required to stop a 50 kg diver who enters the water at 4 m/s and comes to a stop 3 meters underwater. The correct approach involves using the kinematic equation v² - u² = 2ad to determine the acceleration, where v is the final velocity (0 m/s), u is the initial velocity (4 m/s), and d is the distance (3 m). After finding the acceleration, the net force can be calculated using F = ma, where 'm' is the diver's mass and 'a' is the calculated acceleration.

A 50 kg diver enters the water moving at 4 m/s. He eventually comes to a stop 3 meters below the water surface. What amount force brought the diver to a stop?
Homework Equations
Is the acceleration -9.8 m/s^2?
Then, would you use F = ma to find the net force?
The Attempt at a Solution
i tried to do F = (50 kg)(-9.8 m/s^2) but i don't think that's right...
Thank you.
