Estimate the average speed of the apollo spacecaft in m/s, given that the craft took five days to reach the moon from eaeth .the moon is 3.8*10 to the power 8m from earth.
ESTIMATE
distance=400M m
time=5*24=120hrs*3600sec/hr=about 3.6*.12 sec=about .42E6sec
so speedabout=900m/s
about means I rounded and calculated in my head. It is an estimate.
Now more accurately
speed=380E6/(5day*24hr/day*3600sec/hr)
speed=380E6/(5*24*3600)=880 m/s
Well, let's calculate it out. If the moon is 3.8*10^8m away from Earth and it takes 5 days to reach the moon, we can start by figuring out how many seconds are in 5 days. There are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute. So, 5 days is equal to 5 * 24 * 60 * 60 seconds.
Now, if we divide the distance to the moon (3.8*10^8m) by the time it took to reach there (5 * 24 * 60 * 60 seconds), we'll get the average speed.
But wait, let me do the calculations for you... *doing some math*... *carrying the one*... ah, yes!
The estimated average speed of the Apollo spacecraft would be approximately 889.6 meters per second. That's not a bad speed for a trip to the moon! Just make sure you buckle up tightly, as there are no rest stops or drive-thrus along the way.
To estimate the average speed of the Apollo spacecraft, we can use the formula:
Average Speed = Total Distance / Total Time
First, we need to convert the five days into seconds. Since there are 24 hours in a day and 60 minutes in an hour and 60 seconds in a minute, we have:
Total Time = 5 days * 24 hours * 60 minutes * 60 seconds
Total Time = 5 * 24 * 60 * 60 = 432,000 seconds
Next, we need to calculate the total distance between the Earth and the Moon. Given that the Moon is 3.8 * 10^8 meters from Earth, we have:
Total Distance = 3.8 * 10^8 meters
Now we can calculate the average speed:
Average Speed = Total Distance / Total Time
Average Speed = (3.8 * 10^8 meters) / 432,000 seconds
Simplifying the calculation:
Average Speed ≈ 879.63 meters per second
Therefore, the estimated average speed of the Apollo spacecraft is approximately 879.63 m/s.
To estimate the average speed of the Apollo spacecraft, we can use the distance it traveled and the time it took to reach the moon.
Given:
- Time taken to reach the moon = 5 days
- Distance from Earth to the moon = 3.8 × 10^8 meters
To find the average speed, we can divide the distance traveled by the time taken:
Average speed = Distance / Time
Let's calculate it step by step:
Step 1: Convert the time taken to seconds since the distance is given in meters:
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
So, the number of seconds in 5 days = 5 days × 24 hours × 60 minutes × 60 seconds
Step 2: Calculate the average speed:
Average speed = (Distance to the moon) / (Time taken in seconds)
Now, let's perform the calculations:
Step 1:
5 days × 24 hours × 60 minutes × 60 seconds = 5 × 24 × 60 × 60 seconds
Step 2:
Average speed = (3.8 × 10^8 meters) / (5 × 24 × 60 × 60 seconds)
Simplifying the expression:
Average speed = (3.8 × 10^8 meters) / (18,000 seconds)
Now, let's evaluate it:
Average speed = (3.8 × 10^8) / (18,000) meters/second
Calculating the division:
Average speed ≈ 2.11 × 10^4 meters/second
Therefore, the estimated average speed of the Apollo spacecraft is approximately 2.11 × 10^4 meters/second.
