Answer:
[tex]900 \: kg⋅m/s[/tex]
Explanation:
To calculate the momentum, multiply the mass, 300 kg by the velocity, 3 m/s. kg ⋅m/s is an SI unit, or in the International System of Units.
[tex]300 \times 3 = 900 \: kg⋅m/s[/tex]
Answer: the momentum is P = 900kg*m/s westwards
Explanation: Momentum is defined as "the amount of movement", the momentum of an object of mass M that is moving with a velocity V is:
P = M*V
And in this case, we have M = 300kg and V = m/s westward (for example, if we define westward as the positive x-axis, we have V = 3m/s i)
Then the momentum is P = 300kg*3m/s = 900kg*m/s westwards (momentum, like the velocity, also is a vector, so it has an direction).
