What is the instantaneous velocity of a freely falling object 10s after it is released from rest? What is its average velocity during this 10s interval? How far will it fall during this time?

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

If 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.

thank you

my teacher just told me to round it up to 10m/s^2
