Answer:
120 kg.m/s
Explanation:
Momentum is defined as the product of mass and velocity of an object. Velocity in this case considers the direction of movement ie whether East to East or West etc. The formula for momentum is p=mv where p is momentum, m is the mass in kgs, v is the velocity in m/s. Substituting 12 kg for m and 10 m/s for v then momentum will be 12*10=120 kg.m/s
If an object with a mass of 12 kilograms is moving at 10 meters per second, the momentum of the object will be 120kgm/s.
Momentum of a body can be calculated by multiplying the mass of the object by its velocity. That is;
Momentum = mass × velocity
According to this question, the mass of the object is 12kg while its velocity is 10m/s.
Momentum = 12kg × 10m/s
Momentum = 120kgm/s.
Therefore, if an object with a mass of 12 kilograms is moving at 10 meters per second, the momentum of the object will be 120kgm/s.
