Question

the linear momentum of ball of mass 90 g is 0.5 kgms^-1.Find its velocity​

Answer 1

Answer:

5.55 m/s

Explanation:

Given,

Mass(m) = 90g

$=90\times 10^{-3}kg$

= 0.09kg

Linear momentum(p) = 0.5kgm/s

To Find :-

Velocity(v)

Formula Used :-

$p = m\times v$

$\implies v =\dfrac{p}{m}$

Solution :-

$velocity=\dfrac{0.5kgm/s}{0.09kg}$

$=\dfrac{0.5}{0.09}m/s$

$=\dfrac{5\times 10^{-1}}{9\times 10^{-2}}m/s$

$=\dfrac{5}{9}\times 10^{1}m/s$

$=0.555\times 10 m/s$

= 5.55 m/s

Velocity(v) = 5.55 m/s
