Question

1. If a scuba diver steps off the back of a boat and drops straight into the water, determine the resistive force of the water if the mass of the diver and scuba gear is 80 kg, the deck of the boat is 1.75 m above the water’s surface, and the diver comes to rest at a depth of 6 m below the surface of the water after the dive.

Answer 1

$$F_rd=mgh\\(6)F_r=(80)(9.8)(1.75)\\F_r=229\ N$$
