17. Constant acceleration in both directions ( x and y ) allows us to use Table 2-1 for the motion along each direction. This can be handled individually (for Δ x and Δ y ) or together with the unit-vector notation (for Δ r ). Where units are not shown, SI units are to be understood. (a) The velocity of the particle at any time t is given by GG G vv a t =+ 0 , where G v 0 is the initial velocity and G a is the (constant) acceleration. The x component is v x = v 0 x + a x t = 3.00 – 1.00 t , and the y component is v y = v 0y + a y t = –0.500 t since v 0y = 0. When the particle reaches its maximum
