Final answer:
The total momentum of the combined body, with a mass of 8 kg moving at 2 m/s, is 16 kg·m/s.
Step-by-step explanation:
The question at hand is related to momentum, which is a concept in Physics. The momentum of an object is defined as the product of its mass and velocity. In this case, after a 5 kg ball coalesces with a 3 kg ball, we are asked to find the momentum of the resulting combined body if its final speed is 2 m/s.
Using the formula for momentum (p = m * v), we can calculate the momentum as follows:
- Total mass of the combined body = 5 kg + 3 kg = 8 kg
- Final velocity of the combined body = 2 m/s
- Total momentum of the combined body (p) = total mass * final velocity = 8 kg * 2 m/s
Thus, the total momentum of the body is 16 kg·m/s.
