For the average speed I got 50m/s nd for the last one I got 500m

is this right? how do I do the first one? please help

**drwls**, Sunday, October 10, 2010 at 12:03amIf you use the correct value for g, 9.8 m/s^2, you will find that the instantaneous velocity after 10 seconds is 98 m/s. The average velocity is half that.

The distance travelled is time x (avg. velocity) = 490 m

You method of soloution is correct, you just used a different value of g that you may have been told to use.

Thanks for showing your work. I wish more students would do that.
