Question

A .20 kg ball is moving at a speed of 12m/s. what is the momentum of the mall in kg times m/s?

Answer 1

well... momentum is mass times velocity so 0.2 kg * 12 m/s = 2.4 kg m/s

Answer 2

we know that momentum(p)=mass*velocity
=m*v
given:-mass=0.00002g
velocity=12m/sec
momentum=.00002*12
=.000024gram*meter/sec

Answer 3

Be more careful - 0.2 kg = 200 g, not 0.00002 g

\[0.2 kg* 10^{3}g/kg = 200g\]
