PYQ NEET- Rotational Motion L-4

Question: The distance covered by a body of mass $5 \mathrm{~g}$ having linear momentum $0.3 \mathrm{~kg} \mathrm{~m} / \mathrm{s}$ in $5 \mathrm{~s}$ is#

A) $0.3 \mathrm{~m}$

B) $300 \mathrm{~m}$

C) $30 \mathrm{~m}$

D) $3 \mathrm{~m}$

Answer: $300 \mathrm{~m}$#

Solution:#

$\begin{aligned} & P=m v \ & 0.3=5 \times 10^{-3} v \ & v=\frac{0.3}{5 \times 10^{-3}} \ & v=60 \mathrm{~m} / \mathrm{s} \ & S=v \times t \ & =60 \times 5 \ & =300 \mathrm{~m}\end{aligned}$
