Use a landmark along the side of the road.
As the car in front of you passes it start counting.
When you pass the same landmark stop counting.
The number you reach will be the number of seconds (provided you counted at the rate of 1 number per second.)
To find the average speed between time=0 and time=2, divide the distance traveled by the time (in this case 2 seconds).
A stone that falls from a ledge and takes 8 second to hit the ground travels a distance of 313.6 meters. You can find this answer by substituting 8 seconds for time in the physics formula d = 1/2 x acceleration x (t squared), where d = distance, acceleration is given as a =9.8 meters/second squared, and t squared is time in seconds.
first you have to convert the 6 mins to seconds 60 x 6 = 360 + 35 = 395 sooo 8550/395 = 21.65 m/s
Use the known numbers to substitute in the formula distance = rate x time (d=rt) d = r x t 23 = r x 0.28 (then divide both sides by 0.28 to find the rate 23 ÷ .028 = r ÷ .028 82.142857 ft per second = r (round off to 82.14 ft/sec)
There are 60 seconds in a minute, so to find the number of seconds in 30 minutes, you would multiply 60 by 30. This equals 1800 seconds. Therefore, there are 1800 seconds in 30 minutes.
Multiply by a value in seconds, that way you find out the distance. The distance will be in metres which will be travelled in a certain amount of seconds
Distance divided by velocity = time
Read your state's Driver's Manual. You will find that three seconds is rarely ever enough distance.
To find the distance traveled in the first 5 seconds, we multiply the average velocity by the time traveled. If the object's velocity is constant, this distance is equal to the velocity multiplied by the time.
distance = speed x time so the distance is just the speed of the stone x 8 seconds
speed=distance/time taken 600/10= 60m/s
To find the average speed between time=0 and time=2, divide the distance traveled by the time (in this case 2 seconds).
Since light travels at the speed of 299,792,458 m/s, in order to find the distance of a light year (the distance light travels in one year) you must solve the following mathematical equation: 299,792,458 x 60^2(60 squared)x 24 x 365. I believe the answer is 9,444,794,155,488,000 meters. 9,444,794,155,488 kilometers. 9,444 terameters (Tera= one trillion).
You didn't specify what data is given. In general, for constant speed, the following formula is important (just use the definition of speed): speed = distance / time; or distance = speed x time. If distance is in km and time in hours, speed will be in km/hour; if distance is in meters and time in seconds, speed will be in meters/second.
Use the formula: Speed = distance / time. If you divide meters / seconds, the speed will obviously be in meters/second.
"Magnitude" is the size or distance. Its measure depends on the metric that is defined on the relevant space.
To calculate average speed, divide the total distance traveled by the time taken. If you have the distance and time values for the first 4 seconds, you can use this formula to find the average speed over that time interval.
