Answer :
Final answer:
The momentum of probe 1 with a mass of 86 kg and a speed of 11,000 m/s is 946,000 kg·m/s. The correct answer is d. 946,000 kg·m/s.
Explanation:
The momentum of an object can be calculated by multiplying its mass by its velocity. In this case, the mass of probe 1 is 86 kg and its speed is 11,000 m/s. To find its momentum, we multiply the mass and velocity:
Momentum = mass × velocity = 86 kg × 11,000 m/s = 946,000 kg·m/s.
Therefore, the correct answer is d. 946,000 kg·m/s.
Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. See Newton’s laws of motion.
From Newton’s second law it follows that, if a constant force acts on a particle for a given time, the product of force and the time interval (the impulse) is equal to the change in the momentum. Conversely, the momentum of a particle is a measure of the time required for a constant force to bring it to rest.
