Answer 2

Answer:

Time (9.10 - 9.40) = 30 mins = 1/2 hr

Initial velocity = 36 km/h

Final velocity = 72 km/h

acceleration = final velocity - initial velocity/ Time taken

= 72 - 36 / 1/2

= 36

------

1/2

= 36 × 2

= 72 km/hr

m/s. = 72 × 1000/ 3600

ans ; 20 m/s

The S.I unit of acceleration is m/s.
