The movement of a material point is given by the equation x = 2t + 5t ^ 2 find the initial speed.
| February 17, 2021 | education
x (t) = 2 * t + 5 * t ^ 2 – the equation of body motion;
It is required to determine the initial velocity V0.
The general equation of motion looks like this:
X (t) = V0 * t + a * t ^ 2/2.
Substituting the known values, we get:
2 * t + 5 * t ^ 2 = V0 * t + a * t ^ 2/2.
V0 = 2 m / s.
Answer: the initial speed is 2 m / s.
