Physics - Kinematics Question with Solution | TestHub

A particle is moving along the$x$-axis with its coordinate with time$t$given by$x\left(t\right)=10+8t-3t^2.$Another particle is moving along the$y$-axis with its coordinate as a function of time given by$y\left(t\right)=5-8t^3.$At$t=1 \mathrm{s},$the speed of the second particle as measured in the frame of the first particle is given as$\sqrt{v}.$Then$v\left(\mathrm{i}\mathrm{n} \mathrm{m} {\mathrm{s}}^{-1}\right)$is ___________.
