The initial velocity and acceleration of four moving objects at a given instant in time are given in the following table. Determine the final speed of each of the objects, assuming that the time elapsed since t = 0 s is 2.0 s.
___________Initial velocity v0___________ Acceleration a
(a) .............. +12 m/s ..........................+3.0 m/s2
(b) .............. +12 m/s ......................... -3.0 m/s2
(c) .............. -12 m/s .......................... +3.0 m/s2
(d) .............. -12 m/s .......................... -3.0 m/s2 |
