Answer:
Height of rectangular prism = 11 inches
Step-by-step explanation:
Given that:
Volume of rectangular prism = 572 cubic inches
Length of prism = 4 inches
Width of prism = 13 inches
Volume of prism = Length * Width * Height
572 = 4 * 13 * h
572 = 52h
52h = 572
Dividing both sides by 52

Hence,
Height of rectangular prism = 11 inches
Answer: 35.7%
Step-by-step explanation:
140$ / 100% = 1.4$ per 1%
Next 50$ / 1.4% = 35.71
Round 35.71 to closest tenth so it would be 35.7
Answer:
-2

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.
