Question
A point move in a straight line under the retardation av2. If the initial velocity is u, distance covered in ‘t’ seconds : -
Options
A.aut
B.
ln (aut)
ln (aut)C. ln (1 + aut)
ln (1 + aut)D.a ln (aut)
Solution
α = - av2 = 
= - 
dt
⇒ -
= - at ⇒ 
= - at
⇒ v =
dx = 
⇒ x =
[ln (1 + aut)]0t = 
ln (1 + aut)
= - dt⇒ -
= - at ⇒ = - at⇒ v =
dx = ⇒ x =
[ln (1 + aut)]0t = ln (1 + aut)Create a free account to view solution
