Kinetic energy = (1/2) (mass) (speed)²
= (1/2) (1.4 kg) (22.5 m/s)²
= (0.7 kg) (506.25 m²/s² )
= 354.375 kg-m²/s² = 354.375 joules .
This is just the kinetic energy associated with a 1.4-kg glob of
mass sailing through space at 22.5 m/s. In the case of a frisbee,
it's also spinning, and there's some additional kinetic energy stored
in the spin.
Physical, chemical, chemical, physical, I’m pretty sure. Natural things, like you starting to breathe heavier are physical most of the time!!!
Answer:
A
Explanation:
the metal lunchbox has a higher conductivity
<h2 />
Answer:
F = 5291.25 N
Explanation:
F = Ma so 1245 times 4.25^2 ,, that equals 5291.25 N
The unit of measurement of work is the Joules. B.
