The acceleration of the bus is 1.11 meters per second square to the direction of motion
Explanation:
Acceleration is the rate of change of velocity
The formula of the acceleration is , where
is the initial velocity
is the final velocity
- t is the time
A bus that goes from 10 km/h to a speed of 50 km/h in 10 seconds
→ = 10 km/h
→ = 50 km/h
→ t = 10 seconds
Change the unite of the time from seconds to hour
→ 1 hour = 60 × 60 = 3600 seconds
→ 10 seconds = hour
Substitute these values in the formula of the acceleration above
→
→ a = 14400 km/h²
To change the unit of acceleration to meter per second change the
kilometer to meter and the hour to seconds
→ 1 km = 1000 m
→ 1 hour = 3600 seconds
→
→ a = 1.11 m/sec².
