Answer:
Explanation:
The formula for KE is
and we fill in to solve for KE:
I used 2 significant digits in the velocity because 1 isn't accurate enough. Therefore, my answer will be rounded to 2 sig fig's:
KE = 340 J (rounded from 343). And we do the exact same thing in #2:
(Used 2sig fig's for both the mass and the velocity) to get
KE = 63 J (rounded from 62.5)
