Vedclass · Answer

(A) The momentum $P$ of a body is given by the product of its mass $m$ and velocity $v$: $P = m 	imes v$ Given,$m = 3.513\ kg$ (which has $4$ significant figures) and $v = 5.00\ ms^{-1}$ (which has $3$ significant figures). Calculating the product: $P = 3.513 	imes 5.00 = 17.565\ kg\ m/s$ According to the rules of significant figures,the result of a multiplication should have the same number of significant figures as the measurement with the fewest significant figures. Since $5.00$ has $3$ significant figures,we must round the result to $3$ significant figures. Rounding $17.565$ to $3$ significant figures gives $17.6\ kg\ m/s$.

$A$ body of mass $m = 3.513\ kg$ is moving along the $x$-axis with a speed of $5.00\ ms^{-1}$. The magnitude of its momentum is recorded as ........ $kg\ m/s$.
