Answer:
The mass of the object is 300 kg
Step-by-step explanation:
The given parameters are;
The velocity of the object = 5 m/s southeast
The total momentum of the object = 1500 kg·m/s
The equation for linear momentum, is given as follows;
Momentum = Mass × Velocity
Therefore, the mass of the object can be found as follows;
Therefore, we have;
The mass of the object = 300 kg.
