A man is sliding down a pole thru 2.5 meters as shown below. He starts from rest and lands with the speed of 3.1 m/s. Man’s mass is 85 kg.
a) Draw Free Body Diagram of the man sliding down the pole.
b) Find the Friction force exerted on the man by the pole. Use Newton’s 2nd Law of Motion to solve this problem.
c) Determine acceleration of the man sliding down the pole.

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

What organization and environment is described above?

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
