A300 kg tiger is prowling with a velocity of 3 m/s westward. what is the momentum of the tiger?

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).
