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 aquires a max speed v and amax kinetic energy K. If instead the mass intially compresses the spring twice as far. A- Its max speed will be 2v and it's max kenitic energy will be Sqroot(2) K. B- Its max speed will be 4v and it's max kenitic energy will b 2 K. C- Its max speed will be v Sqroot(2) and it's max kenitic energy will b 2 K. D- Its max speed will be 2v and it's max kenitic energy will b 4 K. E- Its max speed will be 2v and it's max kenitic energy will b 2 K.
