Answer:
Step-by-step explanation:
If this is
then you distribute the 3 to both terms inside the parenthesis (the 2 and the c^-5). 2 cubed is 8. The rule for the power to power is that you multiply the powers together to get -15. So the final simplification is
Answer:
that is 149.129 miles (thats the answer)
(a-b)(a+b) because when you reverse the sum you do axa and ax-b xx
What we have so far:
Kinetic energy = 0. The reason behind that is because the beam is not moving at a height of 40m.
Gavity, g = 9.8m/s²
Height = 40m
Potential energy = mgh; this is equal to 0 because m, stands for mass and in this problem, we do not have a value for the mass of the beam. Hence, 0 x 9.8m/s² x 40m = 0. Potential energy = 0.
Solution:
We will use the equation of Total energy:
TE = potential energy + kinetic energy
TE = 0 + 0
∴ TE = 0
The answer is: Assuming no air resistance, the total energy of the beam as it hits the ground is 0.
