a=2m/s u = 10 m/s, t = 5 s v = u + at v= 10+(2×5) v = 20m/s

If it was initially moving along the same line at a velocity at or near the speed of light, then the acceleration of 2m/s/s will have little or no effect. Now, if the object was initially at rest, then its speed (after 2 seconds of acceleration at 2m/s/s) will be 4m/s.

a=2m/s

u = 10 m/s, t = 5 sec

v = u + at

v= 10+2×5

v = 20m/sec
