Acceleration = (change in speed) / (time) = 28/7 = 4 meters per second2
Force = (mass) x (acceleration) = (1,000 x 4) = 4,000 kg-m/sec2 = 4,000 Newtons.
First of all, the speed of light is 3 x 108 meters per second, not 3 x 105.It will take 10 milliseconds for a ray of light to travel 3 x 106 meters at a speed of 3 x 108 meters per second.If the number in the question were correct, which they are not, the answer would be ten seconds.
1000 meters = 1 Kilometer
To convert barrels of JP54 (Jet Fuel) to metric tons, you can use an average density of approximately 0.8 metric tons per cubic meter for jet fuel. Since 1 barrel is about 0.159 cubic meters, 1,000,000 barrels would be approximately 159,000 cubic meters. Multiplying this by the density gives roughly 127,200 metric tons of JP54.
2,100 square meters.
The mechanical advantage (MA) of a ramp is calculated as the ratio of the length of the ramp to its height. Given a ramp length of 10 meters and an MA of 5, the height can be calculated using the formula: height = length / MA. Thus, the height of the ramp is 10 meters / 5 = 2 meters.
2 meters per second
Average speed = 200 meters per 25 seconds It can also be written as 8 meters per second
The average speed of a horse can be calculated using the formula: speed = distance/time. In this case, the horse sprints 100 meters in 4 seconds, so the average speed is 100 meters ÷ 4 seconds = 25 meters per second.
12 meters per second
6.25 meters per second
what is the average speed 34 meters in 10 seconds Average speed is calculated by dividing the distance traveled by the time it took to travel it. In this case, divide 34 meters by 10 seconds to get 3.4 m/s.
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.
To find the average speed of the car, divide the distance traveled by the time taken. In this case, the car travels 500 meters in 20 seconds, so the average speed is 500 meters ÷ 20 seconds = 25 meters per second. Therefore, the car is going at an average speed of 25 m/s.
To calculate the runner's average speed, you would use the formula: speed = distance ÷ time. In this case, the distance is 100 meters and the time is 15 seconds. Therefore, the average speed of the runner would be 100 meters ÷ 15 seconds = 6.67 meters per second.
The car's average speed is calculated by dividing the distance traveled by the time taken. In this case, the average speed would be 25 meters per second (5 meters / 0.2 seconds).
100 meters in 9.77 seconds equates to an average speed of 22.9 mph
Average speed = (total distance) / (total time for the distance) =(16 + 16) / (4 + 2) = (32/6) = 51/3 meters per second
