Question

a bus decreases its speed from 80 kilometre per hour to 60 kilometre per hour in 5 minutes find the acceleration of the bus​

Answer 1

Explanation:

Initial Velocity = 80 km/hr = 80 × 5/18 = 200/9 m/s

Final Velocity = 60 km/hr = 60 × 5/18 = 50/3 m/s

Time = 5 minutes = 5 × 60 = 300 seconds

Acceleration = v - u/t

= 50/3 - 200/9/300

= 150 - 200/9/300

= -50/9/300

= - 50 × 300/9

= -5000/3 m/s²
