DIRECTIONS: On the basis of following diagram/picture answer the questions given below: Trolley X and trolley Y are joined by a stretched spring. Trolley X has twice the mass of trolley Y. When the trolleys are released, the acceleration Of X is \[\text{2 m}/{{\text{s}}^{\text{2}}}\] to the right. What is the initial acceleration of trolley Y to the left?

• A.  \[\text{1m}/{{\text{s}}^{\text{2}}}\]                     
• B.  \[\text{2 m}/{{\text{s}}^{\text{2}}}\]
• C.  \[\text{3 m}/{{\text{s}}^{\text{2}}}\]                    
• D.  \[\text{4 m}/{{\text{s}}^{\text{2}}}\]
