## Essential University Physics: Volume 1 (3rd Edition)

We first find the force due to the impulse: $F=\frac{J}{s}=\frac{1.8\times10^5}{.12}=1,500,000N$ We now find the force of gravity: $F_g=8.7 \times 140 = 1218N$ Comparing these gives the percentage, p: $p = \frac{1218}{1,500,000}\times 100= \fbox{.0812 percent}$
