The figure shows an overhead view of a $0.0220\mathrm{kg}$ lemon half and two of the three horizontal forces that act on it as it is on a frictionless table. Force ${\overrightarrow{\mathbf{F}}}_1$ has a magnitude of $6.00\mathrm{N}$ and is at ${?}_1=32.0^{?}$. Force ${\overrightarrow{\mathbf{F}}}_2$ has a magnitude of $9.00\mathrm{N}$ and is at ${?}_2=30.0^{?}$. In unit-vector notation, what is the third force if the lemon half (a) is stationary, (b) has the constant velocity $\vec{v}=(11.0\hat{i}?12.0\hat{j})\mathrm{m}/\mathrm{s}$, and (c) has the varying velocity $\vec{v}=(12.0t\hat{i}?11.0t\hat{j})\mathrm{m}/\mathrm{s}$, where $t$ is time? (a) Number (b) Number (c) Number $\hat{i}+$ $\hat{i}+$ $\hat{i}+$ $\hat{j}$ Units
