The positon of an object moving along x-axis is given by x(t) = (4.2 t ^(2) + 2.6) m, then find the velocity of particle at t =0s and t =3s, then find the average velocity of particle at t =0 sto t =3s.

1.	The positon of an object moving along x-axis is given by x(t) = (4.2 t ^(2) + 2.6) m, then find the velocity of particle at t =0s and t =3s, then find the average velocity of particle at t =0 sto t =3s.
Answer» Solution :`v (0) =0 MS ^(-1), v (3) = 25.2 ms ^(-1) and BAR v = 12.6 ms ^(-1)`
