The equation of motion of the body has the form s = 30t-0.2t ^ 2 at what moment in seconds the body will stop
| February 23, 2021 | education
To solve the problem, you need to write a formula of the following type, in which you need to find the time:
V = S ‘= 30 – 0.4 * t.
Thus, it turns out that:
V = 0.
Now we need to find the time value:
t = 30 / 0.4;
Let’s calculate the value of the formula:
t = 75 s.
Answer: t = 75 s.
