Question

True or False spring energy questions:
k1 = 2k2 and M1=M2 [ Diagram Attached]

1)The P.E. of M1 when it is at x =A is the same as the P.E. of M2 when it is at x=2A.
2)The K.E. of M2 at x=A·√2 is twice that of M1 at x=0.
3)The velocity of M2 at x=0 is twice the velocity of M1 at x=0.
4)The P.E. of M1 at x=A is the same as the P.E. of M2 at x=A.
5)The K.E. of M1 at x=0 is the same as the P.E. of M1 at x=A.
