Question

calculate the velocity of a toy car of mass 250 g so as to have a momentum of 0.05 kg /m/s

Answer 1

Hope u like my process
=====================

Formula to be used
=-=-=-=-=-=-=-=-=-=-=-
=> Momentum = Mass × velocity

i.e. P = m × v

=> Velocity = Momentum ÷ Mass
__________________________

Given
=-=-=-=-
=> Mass = m = 250 gm = 0.25 kg

=> Momentum required =P = 0.05 kg - s /m

So,..velocity
$= > v = \green{\frac{p}{m}} = \green{\frac{0.05}{0.25 } } = \green{ \frac{1}{5}} = \green{0.2 \: m {s}^{ - 1} }$

So the required velocity ( v) =

$\boxed{ = > v = \underline{ \bf \orange{0.2 \: m {s}^{ - 1} }}}$
