Final answer:
The average acceleration of the bus as it slows down to a stop from 63 m/s to 0 m/s in 13 seconds is -4.846 m/s².
Step-by-step explanation:
To calculate the acceleration of the bus as it slows down to stop, we can use the formula for acceleration:
a = (v_f - v_i) / t
Where:
- a is the acceleration
- v_f is the final velocity
- v_i is the initial velocity
- t is the time over which the change in velocity occurs
In this case, the bus slows down from 63 m/s to 0 m/s over a period of 13 seconds. Plugging these values into the formula:
a = (0 m/s - 63 m/s) / 13 s = -63 m/s / 13 s = -4.846 m/s²
The negative sign indicates that the bus is decelerating. So, the average acceleration of the bus is -4.846 m/s².
