Suppose that a particle moves according to the law of motion s = t* – 8t + 16, t > 0. (A) Find the velocity at time t. v(t) = (B) What is the velocity after 3 seconds? Velocity after 3 seconds = (C) Find all values of t for which the particle is at rest. (If there are no such values, enter 0. If there are more than one value, list them separated by commas.) t = (D) Use interval notation to indicate when the particle is moving in the positive direction. (If the particle is never moving in the positive direction, enter "{}" without the quotation marks.) Answer = (E) Find the total distance traveled during the first 8 seconds. Total distance =
