Two objects of masses
m1 = 0.40 kg
and
m2 = 0.92 kg
are placed on a horizontal frictionless surface and a compressed
spring of force constant
k = 290 N/m
is placed between them as in figure (a). Neglect the mass of the
spring. The spring is not attached to either object and is
compressed a distance of 9.6 cm. If the objects are released from
rest, find the final velocity of each object as shown in figure
(b)....
