as the shuttle bus comes to a sudden stop to aboid hitting a dog, it sccelerates uniformly at -4.1 m/s^2 as it slows from 9.0 m/s to 0 m/s. find the time intercal of acceleration for the bus.

Answer 1

Actually, it is decelerating at a rate of 4.1 m/s^2. The time required = (initial speed)/(deceleration rate)
= 9.0/4.1 = ___ s
