A proton moving along the x axis has an initial velocity of 4.0  106 m/s and a constant acceleration of 6.0  1012 m/s2 . What is the velocity of the proton after it has traveled a distance of 80 cm?
 a. 5.1  106 m/s
  b. 6.3  106 m/s
  c. 4.8  106 m/s
  d. 3.9  106 m/s
  e. 2.9  106 m/s

Question 2

A particle confined to motion along the x axis moves with constant acceleration from x = 2.0 m to x = 8.0 m during a 2.5-s time interval. The velocity of the particle at x = 8.0 m is 2.8 m/s. What is the acceleration during this time interval?
 a. 0.48 m/s2
  b. 0.32 m/s2
  c. 0.64 m/s2
  d. 0.80 m/s2
  e. 0.57 m/s2
