The acceleration of a particle (initially at rest) in an accelerator is described by ax = (22m/s3)t for the first 0 s ≤ t ≤ 0.65 s. For the interval 0.65 s ≤ t ≤ 5.0 s, the acceleration of the particle is modeled by ax = 18.5 m/s2 - (2.2 m/s3)t. Determine the magnitude of a constant acceleration that gives the particle a speed of 35.76 m/s in the same duration as the accelerator. (Hint: how long does the accelerator take in speeding up the particle to 35.76 m/s?)
