The direction of the buoyancy force on a rock that sits on the bottom of a lake is
A. down.
B. up.
C. zero. There is no buoyancy force when the rock is on the bottom.
D. impossible to determine.
Homework Answers
Buoyancy force acts in upward direction due to displacement of fluid by rock.
So direction of buoyancy force on rock is up.
Buoyancy force will try to move rock upwards.
Option B is correct.
Buoyancy acts in up direction.

A man holding a rock sits on a sled that is sliding across a frozen lake...
A man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.480 m/s. The total mass of the sled, man, and rock is 93.5 kg. The mass of the rock is 0.320 kg and the man can throw it with a speed of 16.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in...

A girl stands on the deck of the boat and tosses a rock into a lake. The rock is thrown from a height of 2.50 m above the water surface with a velocity of 4.35 m/s at an angle of 60.0° above the horizontal. As the rock strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the rock enters the...

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...
