Answer:
(1, 3)
Step-by-step explanation:
Solve the following system:
{y - x = 2 | (equation 1)
{x + y = 4 | (equation 2)
Add equation 1 to equation 2:
{-x + y = 2 | (equation 1)
{0 x+2 y = 6 | (equation 2)
Divide equation 2 by 2:
{-x + y = 2 | (equation 1)
{0 x+y = 3 | (equation 2)
Subtract equation 2 from equation 1:
{-x+0 y = -1 | (equation 1)
{0 x+y = 3 | (equation 2)
Multiply equation 1 by -1:
{x+0 y = 1 | (equation 1)
{0 x+y = 3 | (equation 2)
Collect results:
Answer: x = 1, y = 3
Answer:
<em>The magnitude of the velocity will be 60 m/s.</em>
<em>The distance covered is 3,600 m</em>
Step-by-step explanation:
<u>Constant Acceleration Motion</u>
It's known as a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
If a is the constant acceleration, vo is the initial speed, vf the final speed, and t the time, the following relation applies:

The distance traveled by the object is calculated as:

The bus starts from rest, i.e. vo=0, the acceleration is a=0.5 m/s^2. The magnitude of the velocity at t=2 minutes = 120 seconds is:

The magnitude of the velocity will be 60 m/s.
The distance covered during that time is:


x = 3,600 m
The distance covered is 3,600 m
