Answer: [tex]75000kg*m/s[/tex]
Explanation:
[tex]p=mv[/tex]
where;
p = momentum
m = mass = 3000kg
v = velocity = 25m/s
--------------------------------------------------------------------------------------------------
The first thing we need to do is convert 90km/h to m/s. Our conversion factors here are: 1km = 1000m and 1h = 3600s
[tex]90km/h(\frac{1000m}{1km})(\frac{1h}{3600s} )=25m/s[/tex]
Plug your values in the formula:
[tex]p=(3000kg)(25m/s)\\p=75000kg*m/s[/tex]
