A 2.0-kg body moving along the x axis has a velocity vx = 5.0 m/s at x = 0 . The only force acting on the object is given by Fx = (-4.0x) N, where x is in m. For what value of x will this object first come (momentarily) to rest?
 a. 4.2 m
  b. 3.5 m
  c. 5.3 m
  d. 6.4 m
  e. 5.0 m

Question 2

A 10-kg block on a rough horizontal surface is attached to a light spring (force constant = 1.4 kN/m). The block is pulled 8.0 cm to the right from its equilibrium position and released from rest. The frictional force between the block and surface has a magnitude of 30 N. What is the kinetic energy of the block as it passes through its equilibrium position?
 a. 4.5 J
  b. 2.1 J
  c. 6.9 J
  d. 6.6 J
  e. 4.9 J
