JEE MainPhysicsMotion in A PlaneMCQ+4 / −1
At time t=0t=0t=0 a particle starts travelling from a height 7z^ cm7 \hat{z} \mathrm{~cm}7z^ cm in a plane keeping z coordinate constant. At any instant of time it's position along the x^\hat{x}x^ and y^\hat{y}y^​ directions are defined as 3t3 \mathrm{t}3t and 5t35 \mathrm{t}^{3}5t3 respectively. At t = 1s acceleration of the particle will be
