Hi,
I'm having trouble with two physics problems.
- Ashley runs 3.0 km in 4.00 minutes. What is her average velocity? The answer is 45 but I can't figure out how to get it.
- A train moving at 15 km/hr takes 1 minute to come to a stop, find its rate of acceleration, its average velocity and the distance it takes to stop.
Rate of Acceleration
--------------------
15/60 = .25
Average Velocity
----------------
Need help finding this
Distance
--------
15/3.6 = 4.16
4.16 m/s
-------- = .069 m/s^2
60s
Thanks!
