Answer:
5.99 J
Explanation:
A ball is thrown 6m above the ground.
Its total energy at that point is 12 J.
The energy of the ball is given by :
E = mgh
Where
m is the mass of the ball
Let E' is the total energy of the ball at a halfway point of motion. h' = 3 m
So,
So, the required energy is 5.99 J.
Answer: The area of the parking lot is 14,400 meters squared.
Explanation:
We have the dimensions of the parking lot.
60m by 240m
The units used here are meters.
Now, if we want to know the area of the parking lot is equal to the product between the length and the width:
A = 60m*240m = 14,400 m^2
The area of the parking lot is 14,400 meters squared.

As per the question the diagram given is a vertical line.
We are asked to calculate the position of X.
Here the vertical line is divided into many segments.
As per the diagram, it is obvious that the points marked at different positions are separated by four units from each other i.e the distance between two successive marks is 4 units.
The point X is situated at four marks away from 0.
Hence the position of X will be= 4×4 units
= 16 units
Hence the correct answer of this question is D.
