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
