Answer» rong>Question:- → A particle starts from rest and is accelerated uniformly. FIND the RATIO of distance travelled from in3rd and 5th second. Answer:-»»» d3 : d5 = 5 : 9 Solution:-Given:-»»» The body starts from rest. u = 0 »»» The OBJECT is having a uniform acceleration throughout the journey. To Find:-★ The ratio of the distance travelled by the object in 3rd and 5th second. Calculation:-u = 0 ; a = ? S 3 = u + a/2 [2(3) - 1] = a/2 × 5 S5 = u + a/2 [2(5) - 1] a/2 × 9 D3 : D5 a/2 × 5 : a/2 × 9 = 5 : 9 ∴ Ratio of D3 : D5 = 5 : 9 |
