Question

An 850 kg space probe is in outer space and is traveling to mercury at 62,500 km per hour. the engines aren't firing, and gravity is not present. according to newton's first law, how many km per hour will the probe travel in 90 days? a. 61,560 km per hour b. 61,650 km per hour c. 62,410 km per hour d. 62,500 km per hour

Answer 1

With no external forces acting on the space probe, according to Newton's first law of motion, it will continue to move at the same speed of 62,500 km per hour for 90 days and beyond.

Step-by-step explanation:

According to Newton's first law of motion, an object in motion will stay in motion at the same velocity unless acted upon by an external force. In the scenario provided, an 850 kg space probe is traveling to Mercury at 62,500 km per hour, the engines are not firing, and gravity is not present. This means there are no external forces acting on the probe to change its state of motion.

Given these conditions, the space probe will continue to travel at 62,500 km per hour for 90 days or any other amount of time, until an external force acts upon it. So, the correct answer is: d. 62,500 km per hour.

Answer 2

According to Newton's first law of motion, an object in motion will stay in motion at a constant velocity unless acted upon by an external force. In this case, since the engines aren't firing and gravity is not present, the space probe will continue to move at a constant speed.

To find out how far the probe will travel in 90 days, we'll first convert 90 days into hours:

\(90 \text{ days} \times 24 \text{ hours/day} = 2160 \text{ hours}\).

Since the probe is traveling at a speed of 62,500 km per hour, we can now calculate the distance it will cover in 2160 hours:

\(62,500 \text{ km/hr} \times 2160 \text{ hr} \approx 135,000,000 \text{ km}\).

So, according to Newton's first law, the probe will travel approximately 135,000,000 km in 90 days. The closest option to this is not provided among the choices.
