Question

A object decreases its speed from 60 km/h to 20 km/h in 10s find acceleration of bus ? ​

Answer 1

Answer:

acceleration is given by the change in velocity wrt to time.

so the total change in velocity is 30km/s.

acceleration is given by taking care of unit of the time and distance both  

10×3600

30×1000

​  

 =  

12

​  

 in m/s.

Explanation:

just substitute the numbers to get your answer

Answer 2

Explanation:

hence the acceleration is 6.666 m/s^2
