JEE AdvancedPhysicsMotionNumerical+4 / −1
A person of height 1.6 m1.6 \mathrm{~m}1.6 m is walking away from a lamp post of height 4 m4 \mathrm{~m}4 m along a straight path on the flat ground. The lamp post and the person are always perpendicular to the ground. If the speed of the person is 60 cm s−160 \mathrm{~cm} \mathrm{~s}^{-1}60 cm s−1, the speed of the tip of the person's shadow on the ground with respect to the person is ‾cm s−1\underline{\hspace{2cm}}\mathrm{cm}~ \mathrm{s}^{-1}​cm s−1.
