Question 10 You need to drag a very heavy table (m = 57kg) across the kitchen floor, so you apply
a force of 540N (R 35 U]. The floor and the desk create a frictional drag of 325N.

a. Draw a free body diagram showing & labeling all forces and stating their values.

b. What is the net force?

c. What is the coefficient of friction?

d. How long does it take you to drag the table up to a speed of 10.0 m/s starting
from rest?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
