1.   Two  objects of masses  m1  =  0.56 kg  and  m2  =  0.88 kg  are  placed on a  horizontal frictionless surface  and  a  compressed spring  of  force  constant  k  =  280 N/m  is placed between them  as in Fig. a. Neglect the  mass of  the  spring. The  spring  is not attached to either object and is  compressed a  distance  of 9.8  cm.  If the  objects are  released from rest, find the final velocity of each object as shown in Fig. b. 

Two objects of masses m₁ = 0.56 kg m₂ = 0.88 kg are placed on a horizontal frictionless surface and a compressed spring of force constant k = 280 N/m is placed between them as in Figure P6.28a. Neglect the mass of the spring. The spring is not attached to either object and is compressed a distance of 9.8 cm. If the objects are released from rest, find the velocity of each object as shown in Figure P6.28b. 

Two objects of masses m1=0.56kg and m2=0.88kg are placed on a horizontal frictionless surface and acompressed spring of force constant k=280n/m is placed between them as.neglect the mass of the spring, the spring is not attached to either object and is compressed adistance of 9.8cm. if the object are released from rest, find the final velocity of each object 

A 0.47 kg object connected to a light spring with a force constant of 22.0 N/m oscillates on a frictionless horizontal surface. If the spring is compressed 4.0 cm and released from rest. Determine the speed of the object when the spring is compressed 1.5 cm
