Two blocks of masses

m

and

4m

are separately attached to identical horizontal springs of force constant

k

. Both are set into oscillation such that each has the same total mechanical energy. If

v_{1}

and

v_{2}

are their respective maximum speeds, the ratio

v_{1}:v_{2}

is (a)

1:2

(b)

1:\sqrt{2}

(c)

2:1

(d)

1:1
