<p><b>New page</b></p><div>Newton's Second Law can be axpressed as<br />

"During an interval of time a constant force acting on an object causes a change of momentum."<br />
<br />
<math>\vec{F} = {\Delta \vec{p} \over \Delta t}</math><br />
<br />
<math>\Delta \vec{p} = \vec{F} \Delta t</math><br />
<br><br><br />
Given<br />
<br />
<math>\vec{F} = 1000 \cos(127^{\circ}) \hat{i} + 1000 \sin(127^{\circ}) \hat{j} = -600 \hat{i} + 800 \hat{j} N</math><br />
<br><br><br />
we can compute<br />
<br />
<math>\Delta \vec{p} = (-600 \hat{i} + 800 \hat{j})(0.001) = -0.600 \hat{i} + 0.800 \hat{j} N</math></div>imported>Patrick
