Question

 A stone attains a momentum of 1 kg m/s when it flies with a velocity of 2m/s, then what will be mass of the stone?

Answer 1

$\huge\underline{\overline{\mid{\bold{\pink{ANSWER-}}\mid}}}$

Given,

Momentum (p) = 1 kg m/s

Velocity (v) = 2m/s

Mass (m) =?

We know that, Momentum (p) = Mass (m) x Velocity (v)

Therefore, 1 kg m/s = m × 2m/s

$m = \frac{1}{2} = 0.5kg \: = 500gram$

Answer 2

Answer:

Given,

Momentum (p) = 1 kg m/s

Velocity (v) = 2m/s

Mass (m) =?

We know that, Momentum (p) = Mass (m) x Velocity (v)

Therefore, 1 kg m/s = m × 2m/s

m = \frac{1}{2} = 0.5kg \: = 500gramm=21=0.5kg=500gram
