Question

Cross-trained athletes have strong muscles to help them provide enough force to accelerate at high speeds while pushing large weights . After training for two weeks, an athlete gets stronger and can apply more force to the weight. If he can now push the weight 75 meters in 25 seconds, what is his average speed, in meters per second?​

Answer 1

His average speed is 3 meters per second.

Step-by-step explanation:

The average speed is given by:

`\overline{v} = (d_(T))/(t_(T))`

Where:

`d_(T)`: is the total distance

`t_(T)`: is the total time

If he can now push the weight 75 meters in 25 seconds we have:

`d_(T)` = 75 m and
`t_(T)` = 25 s

Hence, his average speed is:

`\overline{v} = (d_(T))/(t_(T)) = (75 m)/(25 s) = 3 m/s`

Therefore, his average speed is 3 meters per second.

I hope it helps you!
