Question

(1)Deduce the second equation of motion graphically? A bus decreases
it's speed from 80km/h to 60km/h in 5 sec.Find the acceleration of the
bus?
​

Answer 1

Answer:

Explanation:

nitial speed   u=80 km/h=80×  

18

5

​  

=22.22 m/s

Final speed    v=60 km/h=60×  

18

5

​  

=16.67 m/s

Using   v=u+at

Or   16.67=22.22+α×5

⟹ a=−1.1 m/
