Aparticle starts from it's origin at t=0 with an initial velocity having an x component of 20m/s and y component of -15m/s. the particle moves in the x-y plane with an x- component of the acceleration only given by ax=4.0m/s. determine the components of the velocity at any time and the total velocity travelled at any time. (b) calculate the velocity of the particle at t=5.0s. (c) determine the x and y coordinates of the particle at t=5.0 s.
