A car starts from rest and moves on a surface in which the co efficient of friction between the road and tyres increases linearly with distance (x) .The car moves with maximum possible acceleration .How will the kinetic energy of the car depend on (x)?

Dear Preeti
= k*x , a = *g = k*x*g
v = u +at = 0 + k*x*g*t
K.E. = E = (1/2) m* v² = (1/2)* m* k²x²g²t²
Proportional to x²
