A body starts slipping down on an incline plane and moves half meter in half second .How long will it take to next half metre?

Dear pallavi

motion for 1/2 meter  

so s= ut +1/2 a t2

 1/2 =0+1/2 * a *(1/2)2

 a=4 m/sec2

now motion for 1 meter

 s= ut +1/2 a t2

 1=0+ 1/2 * 4 *t2

t=1/ √2

so time taken for next 1/2 meter is  t'=1/ √2   -1/2  sec
