The position of a particle moving on a horizontal line where s is in feet to the right of a fixed reference point and t is in seconds after the start of the observation is s t t 5t 24 t 0 3 A Find the velocity in feet per second at time t v t 4 5 B Find the velocity in ft sec of the particle at time t 3 103 C Find all values of t for which the particle is at rest If there are no such values enter none If there are more than one value list them separated by commas t 1 301 D Use interval notation to indicate when the particle is moving in the positive direction If needed enter inf for oo If the particle is never moving in the positive direction enter none 1 301 00 E Find the total distance in feet traveled during the first 8 seconds 4056
