What is the value of the initial velocity of the body if its movement occurs according to the law x = 10 + 3t + 2t ^ 2 (m).
| March 10, 2021 | education
These problems are: the law according to which the coordinate of the considered body changes x = 10 + 3t + 2t ^ 2.
1) We derive the law of speed change: V (t) = x ‘= (10 + 3t + 2t ^ 2)’ = 0 + 3 * 1 + 2 * 2 * t = 3 + 4t.
2) Determine the value of the initial speed: V (0) = 3 + 4 * 0 = 3 m / s.
Answer: The initial velocity of the body in question is 3 m / s.
