If it is starting from rest at 3 meters above the pile, and it drops in freefall, then you can calculated it. Starting from rest, the initial velocity is zero, and the formulas become simpler:

  • distance = (V0*t) + (1/2)*a*t², so V0 = 0.
  • 3 m = (1/2)*(9.8 m/s²)*t² ---> t = 0.78246 seconds

Next: Vf = V0 + a*t = 0 + (9.8 m/s²)*(0.78246 s) = 7.668 m/s.

How do you calculate the speed in meters per second (m/s)?

To calculate speed in meters per second (m/s), you divide the distance traveled in meters by the time taken to travel that distance in seconds. The formula is: Speed (m/s) Distance (m) / Time (s).


How do you calculate linear meters from square meters?

This is an invalid conversion: square meters is a measure of area and meters is a measure of length or distance.


What is the equation used to calculate the distance something travels?

The equation used to calculate the distance something travels is given below . we know, speed = distance /time . distance = speed X time in meters /km /or any other unit of length.


How can I find the speed of an object in meters per second (m/s)?

To find the speed of an object in meters per second (m/s), you can divide the distance traveled by the time it took to travel that distance. The formula for speed is speed distance/time. Simply measure the distance in meters and the time in seconds, then divide the distance by the time to calculate the speed in meters per second.


How to calculate the amount of time for a ball to reach 3 meters?

You need to know how fast the ball is going, and divide the speed by the distance, which is 3 meters.


How do you calculate zip line speed?

To calculate zip line speed, you can use the formula: speed = distance / time. First, measure the total length of the zip line (distance) and then time how long it takes to travel that distance. Ensure that the time is recorded in seconds and distance in meters for consistent units. The resulting speed will be in meters per second (m/s).


When you multiply meters and Newtons do you get joules?

No, multiplying meters and Newtons does not result in joules. Joules are a unit of energy, while meters measure distance and Newtons measure force. To calculate work, which is in joules, you would need to multiply force (in Newtons) by distance (in meters) in the direction of the force.


How do you calculate meters per second?

Speed=Distance/ Time For example: You go 40 meters in 10 seconds. 40/10= 4. So you would be traveling at 4 meters per second.


How do you calculate the number of centimeters if you are given a distance measured in measured in meters?

100 centimeters = 1 meter, multiply by 100.


How much fall is 5 degrees over 1.8 meters?

To calculate the fall over a distance of 1.8 meters for a 5-degree angle, you can use the formula: fall = distance × sin(angle). In this case, fall = 1.8 meters × sin(5 degrees) ≈ 1.8 × 0.0872 ≈ 0.157 meters, or about 15.7 centimeters.


How many laps is 5 meters?

There are no set number of laps for 5 meters, as the lap distance will depend on the size of the track or course you are running on. However, you can calculate how many laps you need to run to cover a specific distance by dividing the total distance by the length of one lap.


How do you calculate the average speed without knowing the speed only the time?

To calculate the average speed of /anything/ you need to know the distance it traveled (IE: 500 meters) and the time it took to travel that (IE:50 seconds) Here's how to calculate it: You take the total distance and divide it by the time. So in our example, a car traveled 500 meters in 50 seconds, so the speed would be: 500 meters / 50 seconds = 500/50 = 10 meters / second. So the car would be traveling 10 meters per second.
