Answer 1

I hope that the enclosed is correct. The acorn seems to pop out of the oak tree. I often wonder how squirrels can eat acorns - I couldn't.
Bon voyage

Answer 4

@osprey I'm getting different answers than yours? I used the help video my teacher put on her board and just replaced the info with what's in the problem and so far I have gotten 1.42s for the first answer and 1.56m for the second answer.?

Answer 5

@osprey even when I input the equation you provided:
\[\sqrt{\frac{ 2 * 10 }{ 9.81 }}\]
I receive an answer of 1.41, not 6.3855s. Not sure how you got 6.3855s for the time, but it messed up the other equations causing everything to be wrong. Luckily I double checked all this before I posted it.

Answer 6

Meant to put *Luckily I double checked all of this before I submitted it to the teacher*

Answer 7

@ltrout Your answers are correct.
The squirrel must run 5 - 1.57 = 3.43 m in 1.42 s to grab the acorn as it reaches the ground.

The 6.4 s answer is a mistake

Answer 8
