A particle moves so that its position as a function of time in SI units is r = i + (3.0) t2 j + t k. Write expressions for its v
maksim [4K]

Answer:

i - component of V is zero for any value of t  i-e  no motion in this direction

Explanation:

Since

r= i+3t^{2}j+t k

==> V = \frac{d r}{dt}=\frac{d(i+3t^{2}j+kt) }{dt}

=6tj+k

and acceleration is given by taking derivative of velocity w.r.t  t

==> a= \frac{dV}{dt}=\frac{d(6tj+k)}{dt}=6j

so, V=0i+6tj+k

and

a = 0i+6j+k

i - component of V is zero for any value of t  i-e  no motion in this direction
