Step-by-step explanation:
We are given that a 20 kg cylindrical mass is dropped onto the mat from a height of 1 m above the mat. During the impact, the cylinder’s vertical velocity reaches zero at the instant the mat has compressed to only 4 cm thick.
So, The Mat gets compressed by : 10cm - 4 cm = 6 cm=0.06 m
a)
Using Conservations of energy
Potential energy at the top = Kinetic energy at the point before touching the surface
Kinetic energy = mgh=
b)
Work done by the mat do to stop the fall of the cylinder =
C)
Work done=
F=3467J
Answer: About
Step-by-step explanation:
The missing figure is attached.
Notice in the first picture that Alberta has a complex shape.
You can calculate the area of a complex shape by decomposing it into polygons whose areas can be calculated easily.
Observe the second picture. Notice that it can be descompose into two polygons: A trapezoid and a rectangle.
The area of the trapezoid can be calcualted with the formula:
Where "h" is the height, "B" is the long base and "b" is short base.
And the area of the rectangle can be found with the formula:
Wkere "l" is the lenght and "w" is the width.
Then, the apprximate area of Alberta is:
Substituting vallues, you get:
Therefore, the area of of Alberta is about .
