A car starts from rest and travels a distance s with a uniform acceleration f, then it travels with uniform velocity for a time t, and at last comes to rest with a uniform retardation (f)/(2) . If the total distance travelled is 5s. Then

1.	A car starts from rest and travels a distance s with a uniform acceleration f, then it travels with uniform velocity for a time t, and at last comes to rest with a uniform retardation (f)/(2) . If the total distance travelled is 5s. Then
Answer» s = ft s = `(1)/(2) ft^(2)` s = `(1)/(4) ft^(2)` s = `(1)/(6) ft^(2)` ANSWER :B
