Calculation of Acceleration of Bus
The problem requires finding the acceleration of a bus that decreases its speed from 80km/h to 60km/h in 5 seconds. The formula to calculate acceleration is:
Acceleration = (Final Velocity - Initial Velocity)/Time
where:
- Final Velocity: 60 km/h
- Initial Velocity: 80 km/h
- Time: 5 sec
Substituting the given values in the formula, we get:
Acceleration = (60 - 80)/5
Acceleration = -4 m/s²
Explanation of Calculation
The negative sign in the answer indicates that the bus is decelerating, which means that its speed is decreasing. The magnitude of acceleration is 4 m/s², which means that the bus is decreasing its speed by 4 meters per second every second.
The formula used to calculate acceleration is derived from the basic equation of motion:
Final Velocity = Initial Velocity + Acceleration * Time
By rearranging the equation, we get:
Acceleration = (Final Velocity - Initial Velocity)/Time
This formula is used to calculate acceleration when the initial and final velocities and the time taken are known.
