A body has uniform acceleration of 45 km min-2 . find the value of ms-2 (S I system).
acceleration [L T-2]
LET L1,T1 DENOTE km & min AND L2,T2 BE DENOTED AS m & sec
IF THE NUMERICAL VALUE IS n1 and n2 RESPECTIVELY
THEN,
n1(L1T1-2) =n2(L2T2-2)
n2 = n1(L1/L2) (T1/T2)-2
SO,
n2 = 45(km/m) /(min/sec)-2
= 45 (103m/m)(60 sec/sec)-2
=( 45* 103)/(60*60)
= 12.5
THUS, ACCELERATION OF THE BODY= 12.5ms-2.
