Need help on Part B and Part C Thanks. In this question the unit vectors i and j are in the directions east and north respectively.A particle R of mass 2kg is moving on a smooth horizontal surface under the action of a singlehorizontal force FN. At time t seconds, the velocity vms of R, relative to a fixed origin O, isgiven by v = (pr -31)i + (81 +q)j, where p and q are constants and p<0.(a) Given that when t= 0.5 the magnitude of F is 20, find the value of p.When t= 0, R is at the point with position vector (2i – 3j) m.(b) Find, in terms of q, an expression for the displacement vector of R at time t.When t = 1, R is at a point on the line L, where L passes through O and the point with positionvector 2i - 8j.(c) Find the value of q.

The equations of motions can be found using:
