-- First of all, an ant sitting 17 cm from the center of a CD remains placidly at rest,
as the radius of a CD is only 6 cm.
-- His old-fashioned cousin, the country ant, sitting 17 cm from the center
of a vinyl record, travels a total distance of (34 pi) cm in each revolution.
If he travels a total of 913 cm in 42 seconds, then his speed per minute is
(913 cm / 42 sec) x (60 sec / minute) = 1,304.286 cm/minute (rounded)
His angular speed is 1,304.286/(34 pi) = 12.21 Rev Per Minute (rounded)
(Country Ant is sitting on the vinyl record that was used for the Saturday night dance
at the church that ended about an hour ago. In use, the record turned at 78 RPM.
After the dance ended and everyone went home, around 9:30, the Victrola eventually
ran out of gas, as there was no one left to crank it up, and it is now coasting to a stop.
In the next 42 seconds, he will travel somewhat less than 913 cm. He is experiencing
a definite case of αλφα ... angular deceleration ... and will wake up feeling quite unwell
in the morning.)

Average speed = Total Distance/Total Time = 350/3 = 116.66... km per hour.
That's a total of 9,600 seconds.
Average speed is total distance divided by total time. Hence 10 metres in 6 seconds is an average speed of (10/6) = 2.66666 m/s. Notice the units of speed - if you ever forget that speed is distance over time, just remember speed's units is something like metres per second, miles per hour etc. "per" means divided by.
To determine who travels more miles per day, we need to calculate the average daily distance traveled by each person. William travels only on Saturdays and Sundays, which means he has a total of 8 days (4 Saturdays and 4 Sundays) to travel 400 miles, averaging 50 miles per day. Jason travels every weekday, totaling 20 days in a month, and has flown 500 miles, averaging 25 miles per day. Therefore, William travels more miles per day than Jason.
Distance = Rate * Timeso,Rate(speed) = Distance/Time= 112 meters/4 seconds= 28 meters/second
The object will move a total distance of 80 meters, which is calculated by multiplying the speed (10 m/s) by the time (8 seconds).
Average speed = (total distance) / (total time for the distance) =(16 + 16) / (4 + 2) = (32/6) = 51/3 meters per second
To get average speed, just divide distance by time. In this case, you divide whatever distance an object moves during the 11 seconds, by the 11 seconds.
The distance-time graph shows that the object initially travels 2 meters in 2 seconds, indicating a speed of 1 m/s for that segment. Subsequently, it travels 80 meters in 40 seconds, resulting in an average speed of 2 m/s for that segment. Overall, the graph reflects two different speeds during the object's journey, with the second segment being slower than the first. The overall distance covered is 82 meters in a total of 42 seconds.
An element of total stopping distance is the reaction distance, which is the distance your vehicle travels from the moment you see a hazard until you physically apply the brakes. This, combined with the braking distance (the distance your vehicle travels once the brakes are applied until it comes to a complete stop), makes up the total stopping distance.
In general, we will find the average speed of a moving object by dividing the total distance it travels by the total time elapsed in its travel.We can find the actual speed of the object if it moves with a constant speed during all of its travel. But if the object is something like a bus or train that makes stops along the way, we discover its average speed by dividing the total distance it travels by the total time it took to travel that distance.
it helps a lot
Average speed = (distance covered) divided by (time to cover the distance) = 30/5 = 6 meters per second.Equivalent to 21.6 km per hour.
To find the average speed from 4 seconds to 8 seconds, you need the total distance traveled during that time interval and the total time taken. The average speed is calculated by dividing the total distance by the total time (4 seconds in this case). If you provide the distance traveled during that period, I can help you calculate the average speed.
To find the average velocity of the car over the entire 10 seconds, we calculate the total displacement and divide it by the total time. The car travels -50 meters in the first 5 seconds and 10 meters in the next 5 seconds, resulting in a total displacement of -50 + 10 = -40 meters. The total time is 10 seconds. Therefore, the average velocity is -40 meters / 10 seconds = -4 meters per second.
One element of total stopping distance is the perception-reaction distance, which is the distance a vehicle travels from the moment a driver perceives a hazard until they physically react by applying the brakes.
