The body, moving from a state of rest, acquired a speed of 6 m / s in 4 s. Determine the acceleration with which the body was moving and the path traveled by the body.
To find the constant acceleration of a moving body and its distance traveled, we use the formulas: a = V / t and S = V * t / 2.
Values of variables: V – acquired speed (V = 6 m / s); t – movement time (t = 4 s).
Calculation: a) constant acceleration: a = V / t = 6/4 = 1.5 m / s2;
b) distance traveled: S = V * t / 2 = 6 * 4/2 = 12 m.
Check: S = V ^ 2 / 2a = 6 ^ 2 / (2 * 1.5) = 12 m (correct).
Answer: The body moved with an acceleration of 1.5 m / s2 and traveled a distance of 12 m.
