Question: Find the average force that a 6 x 101 kg runner exerts on the road in order to go from a velocity of 2

Find the average force that a 6 x 101 kg runner exerts on the road in order to go from a velocity of 2 m/s to 8 m/s over a distance of 25 m. The runner is experiencing a resistance of 30 N in the form of a headwind. You are able to swim at a speed of 1.85 m/s. There is a river next to you that has a current of 1.20 m/s to the west. If you swam across at max speed with the current, how fast would you travel according to someone watching from the shore? If you swam directly against the current, how fast would you travel according to someone watching from the shore? If you swam directly across the river, how fast would you travel according to someone watching from the shore?
