(adsbygoogle = window.adsbygoogle || []).push({}); A chipmunk drops an acorn from a branch 6.0 m above the ground.

a) How long is it in the air?

b)How fast is it going when it hits the ground?

I decided my given was

a=9.8m/s^{2}

d= 6.0 m

v_{i}= 0 m/s

So I used the distance formula (d=v_{i}+1/2*a*t^{2}) and solved for time. I got about 1.1 s.

For the next part I used v_{f}=v_{i}*t+a*t and solved.

I got

a)1.1 seconds

b) 10.78 m/s

Is this correct?
