A rock of mass m = 1.05 kg is dropped from a height of h = 3.9 m into a pool of water. At a time of t = 1.86 s after striking the surface of the water, the rock's velocity has decreased by 50%.
What is the magnitude of the average force the rock experiences, in newtons, during the time t?

Imagine that we release a rock of mass m (which is initially at rest) at the surface of a lake and measure its position and velocity as functions of time while it sinks. The rock moves under the influence of three forces: gravity, buoyancy, and viscous drag. Let y represent the vertical position of the sinking rock, with the surface of the lake at y -0, and positive y upwards The net force on the rock is F =-[m-mdisplaced where...
