The position of an object moving along x axis given by x = a+bt2, where a = 8.5 m and b= 2.5 m/s2 and t measured in sec. what is the velocity at t = 2 s.

v = 10m/s

diffrentiate x = a+bt2 by dt , therefore v=2bt...substuting b=2.5, t=2, ....we get v=10m/s....., plzz don't post questions in the community shelf,.... post it for disscussion with community...
