Suppose a treadmill has an average acceleration of .0050 m/s2. How much does it's speed changer after 4.8 minutes?
avanturin [10]
This one is nice and straight forward :)

simply calculate how many seconds are in 4.8 minutes like this:
4.8min x 60s = 288s

Then to find the ∆v (∆v = symbol for change in velocity) multiply the acceleration 0.0050m/s^2 by 288s
∆v = 1.44m/s



0.0050m/sx^{2}

Our resources can only supply a small fraction of our wants. true false
igor_vitrenko [27]
It is false that our resources can only supply a small fraction of our wants.
Although many resources we have are not renewable, we still have enough goods to meet our every need, at least for now. It may not be so in the future, but for now, we are good.
