University Physics I · Momentum, impulse, and collisions
Impulse from a triangular force pulse
Problem
Work in an inertial laboratory frame, taking $+x$ right and $+y$ upward when components are needed. Treat the named interacting bodies as the system during the stated interval, use SI units, and include every stated external impulse. A force in $+x$ rises linearly from zero to $8\,\mathrm N$ over $0.20\,\mathrm s$ and then falls linearly to zero over the next $0.30\,\mathrm s$. Find its impulse.
Hint
The entire pulse forms a triangle of base $0.50\,\mathrm s$.
