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
elocity and its acceleration as functions of time. Evaluate for t = 5.1 s. i-component of velocity?
1 answer:
Answer:
i - component of V is zero for any value of t i-e no motion in this direction
Explanation:
Since
r= i+3
j+t k
==> V =
=
=
and acceleration is given by taking derivative of velocity w.r.t t
==> a=
=
=
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

The answer to your question is true
Answer:
if it's velocity u talking of.....
Explanation:
then it's displacement/ time
