Answer:

5m/s²

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • Initial Velocity = 40m/s
  • Final velocity = 60 m/s
  • Time = 4s

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>

  • The acceleration .

<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>

We know that the rate of change of velocity is called acceleration. Therefore ,

\sf\implies a = v - u / t \\

\sf\implies a = 60m/s - 40m/s/ 4 \\

\sf\implies a = 20m/s \div 4 \\

\bf\implies a = 5m/s^2

Draw a figure to fit each description.
antiseptic1488 [7]
1)
a) Draw the axis:x-axis is horizontal, y-axis is vertical
b) draw a point on any part of the plane (use color to highlight it)
c) draw a second point on a different part of the plane (again use color)
d) draw the straight line that passes through the two points (use a ruler).

That is it.

2)
a) Draw the axis: x-axis is horizontal and y-axis is vertical
b) Draw a stright line (use a ruler)
c) Draw a second straight line (use a ruler) which is not parallel to the first line. Extend the second line intil it intersects (and passes) the first line. The lines can only intersect in one point (if the lines are parallel they will not intersect each other).

Explain how 49. 567 is done in fraction form
pav-90 [236]
<span>= 49567/1000

</span>rite the decimal number as a fraction
(over 1)
49.567 = 49.567 / 1

Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's

Numerator (N)
N = 49.567 × 10 × 10 × 10 = 49567
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000

N / D = 49567 / 1000

Simplifying our fraction
