As we know that $\Delta v=v_2-v_1$ $\Delta v=\sqrt{v_1^2+v_2^2-2v_1v_2cos(\theta)}$ We plug in the known values to obtain: $\Delta v=\sqrt{(15)^2+(19)^2-2(15)(19)cos(28)}$ $\Delta v=9.095\frac{Km}{s}$ $\Delta v=9095\frac{m}{s}$ Now we can find the acceleration as $a=\frac{\Delta v}{\Delta t}$ $a=\frac{9095}{10\times 60}=15\frac{m}{s^2}$
