Answer 1

Answer:

ANSWER

(a) Consider a body having initial velocity 'u'. Suppose it is subjected to a uniform acceleration 'a' so that after time 't' its final velocity becomes 'v'. Now, from the definition of acceleration we know that:  

Acceleration =  

Time taken

Change in velocity

​  

 

or Acceleration =  

time taken

Final velocity- Initial velocity

​  

 

So, a=  

t

v−u

​  

 

at=v−u

and, v=u+at  

where v= final velocity of the body

u= initial velocity of the body

a= acceleration

and t= time taken  

(b) Initial velocity, u=54km/h=15m/s

Final velocity, v=0m/s

Time, t=8s

Acceleration, a=?

a=  

t

v−u
