Complete question:
If the swimmer could cross a 14 km channel maintaining the same average velocity as for the first 50 m in the pool, how long would it take?
For the first 50m in the pool, the average velocity was 2.08 m/s
Answer:
It would take for the swimmer approximately 1.87 hours.
Explanation:
If the swimmer maintains the average velocity on the channel, we should find and approximate value of the time it takes to cross the channel with the Galileo’s kinematic equation:
With x the displacement, v the average velocity and t the time, solving for t:

50N is your force and the acceleration is -9.8m/s^2 due to gravity.
So, you just plug that in.
BUT you know that mass cannot be negative, so you just disregard the negative sign and the mass of the rock is 5.102 grams.
