NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The acceleration of a particle is defined by the relation a = 9 - 31, where a and tare expressed in ft/s and seconds, respectively. The particle starts at t=0 with v=0 and x = 6 ft. Problem 11.011.b - Particle motion: Integration of velocity to obtain position. Determine the position and velocity when t=4 s. (You must provide an answer before moving to the next part.) The position is ft. The velocity is ft/s. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
