A horizontal force of 1000 N is needed to overcome the force of static friction between a level floor and a 250-kg crate. If g = 9.8 m/s2, what is the coefficient of static friction?
 a. 4.0
  c. 0.41
  b. 0.51
  d. 0.31

Question 2

A block of mass 5.00 kg rests on a horizontal surface where the coefficient of kinetic friction between the two is 0.200 . A string attached to the block is pulled horizontally, resulting in a 3.00 m/s2 acceleration by the block. Find the tension in the string. (g = 9.80 m/s2)
 a. 0.200 N
  c. 19.8 N
  b. 9.80 N
  d. 24.8 N
