I hate physics…please help me!?
During a baseball game a runner traveling at 4.0 m/s slides into second base. Given that it takes her 0.50 s to come to rest, what was her average acceleration?
Approximately how fast was she moving 0.22 s into the slide?
I got her average acceleration; it’s -8 m/s^2
and I keep getting -1.76 m/s for the 2nd question, but my online hw says that’s wrong. Help?

You have to add the intitial velocity. She’s not starting at 0 m/s. She’s starting at 4 m/s. 4-1.76=2.24 m/s.

No, I hate the Cubs the main, then the Twins, then the purple Wings, then the Packers so i assume I hate 2 communities from baseball before I hate communities from the different interest. i’m a White Sox, Blackhawks, Bears fan btw.

use the formula a= (v-u)/t
-8 = (v-4)/0.22
-8(0.22)= v-4
v= 4 – 8(0.22)
=2.24
