320 meters
If an object travels at an average speed of 31 meters per second, you can calculate the distance it would cover in 30 seconds using the formula: distance = speed × time. Thus, distance = 31 meters/second × 30 seconds = 930 meters. Therefore, the object would travel 930 meters in 30 seconds.
To find the time it takes to travel 100 meters at an average speed of 0.5 meters per second, you can use the formula: time = distance/speed. Plugging in the values, time = 100 meters / 0.5 meters per second, which equals 200 seconds. Therefore, it will take 200 seconds for the object to move 100 meters.
The average speed is 5 metres per second.
To find the speed of an object, you can use the formula: speed = distance/time. In this case, the object travels 100 meters in 50 seconds. Therefore, the speed is 100 meters ÷ 50 seconds = 2 meters per second.
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.
If an object travels at an average speed of 31 meters per second, you can calculate the distance it would cover in 30 seconds using the formula: distance = speed × time. Thus, distance = 31 meters/second × 30 seconds = 930 meters. Therefore, the object would travel 930 meters in 30 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.
To find the time it takes to travel 100 meters at an average speed of 0.5 meters per second, you can use the formula: time = distance/speed. Plugging in the values, time = 100 meters / 0.5 meters per second, which equals 200 seconds. Therefore, it will take 200 seconds for the object to move 100 meters.
The average speed is 5 metres per second.
3.00 m/s
To find the speed of an object, you can use the formula: speed = distance/time. In this case, the object travels 100 meters in 50 seconds. Therefore, the speed is 100 meters ÷ 50 seconds = 2 meters per second.
The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
The final velocity of an object in free-fall after 2.6 seconds is approximately 25.48 m/s. The distance the object will fall during this time is approximately 33 meters.
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.
During the 5 seconds, gravity adds 5G = (5 x 9.78) = 48.9 meters/sec to the object's downward speed.During that time, it's average downward speed is 1/2 of [ Vi + (Vi + 48.9) ] = Vi + 24.45 m/s.In 5 seconds it falls 5(Vi + 24.45) = 5Vi + 122.25 meters.5Vi + 122.25 = 240 meters5Vi = 240 - 122.25 = 117.75 metersVi = 117.75 / 5 = 23.55 meters per sec.
The average constant speed of the object between 2 and 5 seconds is the total distance covered divided by the time elapsed. If you have the distance covered during this time interval, divide it by 3 seconds (5s - 2s) to get the average constant speed.
