. Draw a Cartesian coordinate system on a sheet of paper. On this Cartesian coordinate system, draw each vector to scale, starti
1 answer:
Answer:
a) the first vector has magnitude 58 cm and the angle is 15 measured clockwise from the positive side of the x-axis
b) the second vector, the magnitude is 55.7 cm and the angle is 35 half from the negative side of the x-axis in a clockwise direction
c) the magnitude is 54.2 cm with an angle of 18 measured counterclockwise from the x-axis
Explanation:
For this exercise we draw a Cartesian coordinate system in this system: East coincides with the positive part of the x-axis and North with the positive part of the y-axis.
a) the first vector has magnitude 58 cm and the angle is 15 measured clockwise from the positive side of the x-axis
b) the second vector, the magnitude is 55.7 cm and the angle is 35 half from the negative side of the x-axis in a clockwise direction
c) the magnitude is 54.2 cm with an angle of 18 measured counterclockwise from the x-axis
In the attachment we can see the representation of the three vectors

The amount of potential energy the block contains is 2,822.4 Joules
<u>Given the following data:</u>
- Mass of block = 12 kg
- Height of platform = 24 meters.
We know that the acceleration due to gravity (g) of an object on planet Earth is equal to 9.8 .
To determine the amount of potential energy the block contains:
Mathematically, potential energy (P.E) is given by the formula;
Where:
- m is the mass of object.
- g is the acceleration due to gravity.
- h is the height of an object.
Substituting the parameters into the formula, we have;
Potential energy (P.E) = 2,822.4 Joules
