Straight LineEasy
Question
Two points A and B move from rest along a straight line with constant acceleration f and f′ respectively. If A takes m sec. more than B and describes ′n′ units more than B in acquiring the same speed then
Options
A.(f - f′)m2 = ff′n
B.(f + f′)m2 = ff′n
C.
(f + f′)m = ff′n2
(f + f′)m = ff′n2D.(f + f′)n = ff′m2
ff′m2Solution
v2 = 2f(d + n) = 2f′d
v = f′(t) = (m + t)f
liminate d and m we get
(f′ - f)n =ff′m2.
v = f′(t) = (m + t)f
liminate d and m we get
(f′ - f)n =
ff′m2.Create a free account to view solution
