The acceleration can be calculated using the formula:
acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 80 m/s
Final velocity (v) = 60 m/s
Time (t) = 5 s
Let's substitute the values into the formula:
acceleration = (60 - 80) / 5
Simplifying the equation:
acceleration = -20 / 5 = -4 m/s²
Therefore, the acceleration of the bus is -4 m/s². Note that the negative sign indicates that the bus is decelerating (slowing down).
A bus decreases its speed from 80 m/s to 60 m/s in 5s. Find the acceleration of the bus.
