Answer:
As per the statement:
A 900-kg giraffe runs across a field at a rate of 50 km/hr.
⇒ m = 900 kg and
[tex]v=50 km/hr[/tex]
Use conversion:
[tex]1 km/hr = \frac{5}{18} m/s[/tex]
[tex]v = 50 \times \frac{5}{18} = \frac{250}{18} m/s[/tex]
The magnitude of its momentum is given by:
[tex]p = mv[/tex]
where
m is the mass in kg
v is the speed in m/s
Substitute the given value we have;
[tex]p = 900 \times \frac{250}{18} = 50 \times 250 = 12500 kg m/s[/tex]
Therefore, the magnitude of its momentum is 12500 kg m/s
The real answer is 45,000 because i look at this to get the answer and it wasn't on there so i guessed and i got it right.
