A distance-time graph indicates than an object moves 100 m in 4 s and then remains at rest for 6 s. What is the average speed of the object?
avg speed = d/time = 100 m/10 sec = 10 m/s
To find the average speed of the object, we need to divide the total distance traveled by the total time taken.
In this scenario, the object moves 100 m in 4 s and remains at rest for 6 s. Therefore, the total distance traveled is 100 m and the total time taken is 4 s + 6 s = 10 s.
To calculate the average speed, we divide the total distance by the total time:
Average Speed = Total Distance / Total Time
Average Speed = 100 m / 10 s
Calculating this, we get:
Average Speed = 10 m/s
Therefore, the average speed of the object is 10 m/s.
