Question

What is the acceleration of a bus whose speed changes from 10 m/s to 30 m/s over a period of 40 seconds.

Answer 1

The acceleration of the bus is 0.5 m/s².

Step-by-step explanation:

To find the acceleration of the bus, we can use the formula:

acceleration = (change in velocity) / (change in time)

Given that the initial speed of the bus is 10 m/s, the final speed is 30 m/s, and the time taken is 40 seconds, we can substitute these values into the formula:

acceleration = (30 m/s - 10 m/s) / 40 s

The change in velocity is 20 m/s, so the acceleration is:

acceleration = 20 m/s / 40 s

Simplifying the expression gives us:

acceleration = 0.5 m/s²
