I have this question about vectors that I can't quite understand how to do. I can answer part (a) but not (b) or (c), if anyone can help I would be more than grateful!
A particle starts from rest and moves with constant acceleration. After 5 seconds its velocity is (3 4) ms-1 (this is a vector).
(a) find the acceleration of the particle.
(b) find the displacement vector of the particle from its starting position after 5 seconds.
(c) find the distance travelled by the particle after 5 seconds.
As acceleration is constant and the particle starts from rest, $\vec v=\frac 35ti+ \frac 45tj$. You can calculate displacement using integration from $t=0$ to $t=5$. Can you take it from here?
