Initial velocity(u)= 50m/s. t=2s. a= -9.8m/s². ( minus because acceleration is in downward direction). v=u+at. v= 50 - 9.8×2. v= 30.4m/s.
Answer:
- The formula its
- After 5 years, the computer value its $ 1056
Explanation:
<h3>
Obtaining the formula</h3>
We wish to find a formula that
- Starts at 2816.
- Reach 0 at 8 years.
- Depreciates at a constant rate. m
We can cover all this requisites with a straight-line equation. (an straigh-line its the only curve that has a constant rate of change) :
,
where m its the slope of the line and b give the place where the line intercepts the <em>y</em> axis.
So, we can use this formula with the data from our problem. For the first condition:
So, b = $ 2816.
Now, for the second condition:
So, our formula, finally, its:
<h3>After 5 years</h3>
Now, we just use <em>t = 5 years</em> in our formula
Answer:
40.34 s
Explanation:
Given,
Velocity (v) = 5.33 m/s
Distance (s) = 215 m
Time (t) = ?
We know that,
Speed (v) = distance (s)/time (t)
⇒ time(t) = distance (s)/speed (v)
= 215/5.33 = 40.34 sec
∴ time(t) = 40.34 sec.
