1. The change in velocity of a motor bike is 54 kmh in one minute. Calculate its acceleration in
(a) ms? (b) kmh-1
|(a) 0.25 ms? (b) 3240 kmh4​

Answer 1

Answer:

Given,

Velocity of the motorbike is $$54km/hr

So, the acceleration in  k/hr  

2

 is:

60

1

​  

56

​  

=54×60

=3240km/h  

2

 

And,

The acceleration in m/s  

2

 is:

3600×3600

3240×1000

​
