Starting from rest, what is the shortest time this truck could accelerate uniformly to 38.0 m/s (≈ 85.0 mph ) without causing the box to slide. (hint: first use newton’s second law to find the maximum acceleration that static friction can give the box, and then solve for the time required to reach 38.0 m/s .)
