Physics - Kinematics Question with Solution | TestHub

A bird is at a point $\mathrm{P}(4,-1,-5)$ and sees two points ${\mathrm{P}}_1(-1,-1,0)$ and ${\mathrm{P}}_2(3,-1,-3)$. At time $\mathrm{t}=0$, it starts flying with a constant speed of $10\mathrm{m}/\mathrm{s}$ to be in line with points ${\mathrm{P}}_1$ and ${\mathrm{P}}_2$ in minimum possible time t . Find $t$ (in sec), if all coordinates are in kilometers.
