Physics - SHM Question with Solution | TestHub

A particle of mass $m=2$ kg executes SHM in the $xy$-plane between points $A$ and $B$ under a force $\overrightarrow{F}=F_x\hat{i}+F_y\hat{j}$. The minimum time to move from $A$ to $B$ is 1 s. At $t=0$ the particle is at $x=2$, $y=2$ (Figure 5.130, $A(2,2)$, $B(-2,-2)$). Then $F_x$ as a function of time $t$ is:
