Question

please help...
A 60 kg zebra is traveling 9 km/hr east. What is the zebra’s momentum? kg-m/s

Answer 1

Momentum = mass • velocity

Answer 2

Now, do you think you can figure it out?

Answer 3

540

Answer 4

1 km=1000 m
1 hr =3600 s
\[km/hr=\frac{ 1000 }{ 3600 }\]
\[v=9 km/hr=\frac{ 9 \times 1000 }{ 3600 }=\frac{ 5 }{ 2 }~m/s\]
momentum=mass*velocity
\[=60 \times \frac{ 5 }{ 2 }=? kg~ m/s\]
