Answer:
True
Step-by-step explanation:
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.
Answer: 10,883.6
Step-by-step explanation: So first we have to find out what the depreciation is and to find that we have to take the 20,930 and times it by 0.06 (6%) which is 1,255.8,
So, we then times 1,255.8 by 8 because 8 years of depreciation, which is 10,046.4,
Finally we take 20,930 (the cars total value) and subtract the depreciation from it (10,046.4) so in 8 years the car is worth 10,883.6
