Two masses 10kg and 20kg are connected by a massless string. A force of 200N acts on 20kg mass. At that instant when 10kg mass has an acceleration 12m/s^2 the energy stored in the spring (k=2400N/m) will be

Question

Khimraj · Answer

Acceleration of 10kg mass =12m/s² Force=ma F=10x12=120N will act . Net force on 20kg mass will be : 200N-120 N=80N a=F/m =80/20 =4m/s² ∴ The acceleration of 20kg mass is 4m/s²
