A mass is pressed against (but is not attached to) an ideal horizontal spring on a frictionless horizontal surface. After being released from rest, the mass acquires a maximum speed v and a maximum kinetic energy K. If instead the mass initially compresses the spring twice as far:.
(a) its maximum speed will be 2v and its maximum kinetic energy will be 4K.
(b) its maximum speed will be 2v and its maximum kinetic energy will be โˆš2K.
(c) its maximum speed will be 4v and its maximum kinetic energy will be 2K.
(d) its maximum speed will be 2v and its maximum kinetic energy will be 2K.
(e) its maximum speed will be v โˆš2 and its maximum kinetic energy will be 2K.
