$F_x~t = \Delta p_x$ $F_x~t = m(v_{x2}-v_{x1})$ $F_x = \frac{m(v_{x2}-v_{x1})}{t}$ $F_x = \frac{(0.145~kg)[(52.0~m/s)~cos(30^{\circ})-(-40.0~m/s)]}{0.00175~s}$ $F_x = 7050~N$ $F_y~t = \Delta p_y$ $F_y~t = m(v_{y2}-v_{y1})$ $F_y = \frac{m(v_{y2}-0)}{t}$ $F_y = \frac{(0.145~kg)[(52.0~m/s)~sin(30^{\circ})]}{0.00175~s}$ $F_y = 2150~N$
