What is the value of the initial velocity of the body if its movement occurs according to the law x = 2t ^ 2 – 3t + 8 (m)? Write the equation of the dependence V (x) = V (t).
The speed V (t) is equal to the derivative of x (t) with respect to time t. That is
V (t) = (2t ^ 2 – 3t + 8) ‘= 4t – 3.
Initial velocity Vo = V (0) = 4 * 0 – 3 = -3 m / s.
