A particle P is moving along a straight line with a velocity of `3ms^(-1)` and another particle Q has a velocity of `4ms^(-1)` at an angle of `30^(@)` to the path of P. Find the speed of Q relative to P.

A particle moves in a straight line with an acceleration a ms^(-2) at time 't' seconds where a =-(1)/(t^(2)) . When t = 1 the particle has a velocity of 3ms^(-1) then the velocity when t = 4 is (v)/(4) . Find the value of v.
