The momentum of a 5kg object that has a velocity of 1.2m/s is 6.0kgm/s.
<h3> MOMENTUM:</h3>
Momentum of a substance is the product of its mass and velocity. That is;
Momentum (p) = mass (m) × velocity (v)
According to this question, an object has a mass of 5kg and velocity of 1.2m/s. The momentum is calculated thus:
Momentum = 5kg × 1.2m/s
Momentum = 6kgm/s.
Therefore, the momentum of a 5kg object that has a velocity of 1.2m/s is 6.0kgm/s.

Answer:
m = 1.64 kg
Explanation:
Given that,
The work done to lift a body, W = 1,033 J
Height, h = 64 m
We need to find its mass. The work done in lifting the mass is given by :
Hence, the mass of the body is 1.64 kg.
