    Projectile motion and range

    3 . A particle starts from the origin at t=0 with an initial velocity having an x-component of 20m/s and a y-component of -15m/s. The particle moves in the xy plane with an x component of acceleration only, given by ax = 4.0m/s2 a)Determine the total velocity vector at any time b)Calculate the...
