Question

The position vectors of a particle is $\vec{r}=6 \mathrm{ti}+4 \mathrm{t}^{2} \mathrm{j}+10 \mathrm{k}$. The velocity of the particles at the initial instant is\

Professor PC Thomas Classes · Answer

Velocity vector $\mathrm{v}=\frac{\mathrm{dr}}{\mathrm{dt}}=6 \mathrm{i}+8 \mathrm{tj}$ Initial velocity ( $\mathrm{t}=0$ )\ $\mathrm{V}(0)=6$\
