| What path has the body traveled during the time during which its speed has increased from 4 to 12 cm / s, if the acceleration is 2 cm / s2.
Initial data: V1 (body speed before acceleration) = 4 cm / s; V2 (body speed after acceleration) = 12 cm / s; a (body acceleration) = 2 cm / s.
The distance that the body will travel with an increase in its own speed can be calculated by the formula: S = (V2 ^ 2 – V1 ^ 2) / 2a.
Let’s do the calculation: S = (12 ^ 2 – 4 ^ 2) / (2 * 2) = 128/4 = 32 cm.
Answer: The body has traveled a path of 32 centimeters.
