Question

A particle moves in a straight line, its position (in m) as function of time is given by

x = (at2

+ b)

What is average velocity in time interval t = 3 sec to t = 5 sec in m/s. (Where a and b are constants and

a = 1 m/s2

, b = 1 m.) also find instantaneous velocity at t = 3 sec. & t = 5 sec.​
