Question
A particle moves along an arc of a circle of radius R. Its velocity depends on the distance covered s as v = a√s, where a is a constant then the angle between the vector of the total acceleration and the vector of velocity as a function of s will be
Options
A.tan α = R/2s
B.tan α = 2s/R
C.tan α = 2R/s
D.tan α = s/2R
Solution
v = a√s ⇒ v2 = a2 s
at =
= 
aC =
