In previous question, if the total distance covered by the car is s, the maximum speed attained by it will be :

Answer»

`(2S.(a_1a_2)/(a_1+a_2))^((1)/(2) ) `
` (2s.(a_1a_2)/(a_1-a_2) )^((1)/(2))`
` ((s)/(2) .(a_1a_2)/(a_1+a_2))^((1)/(2)) `
` ((s)/(2) .(a_1a_2)/(a_1-a_2))^((1)/(2)) `

SOLUTION :` S = (1)/(2) (t_1+t_2) V_m "","" S= (1)/(2) ((V_m)/(a_1)+(V_m)/(a_2) ) V_m `
` ""S= (VM^(2))/(2) ((1)/(a_1)+(1)/(a_2)) ,"" V_m =(2s (a_1a_2)/(a_1+a_2)) ^(1//2)`
