Question

Two masses of 10kg and 5kg are suspended from the rigid support
The system is pulled down with a force of 150N attached to the
lower mass The string attached to the support breaks and the system
accelerates downwards Incase the force continues to act what willbe
the tension acting between the two masses?

Vara · Accepted Answer

Acceleration of the system:
a=Fnetm1+m2 =F+m1+m2gm1+m2 =150+10+51010+5 =20 m/s2

Equation for lower body of mass 5 kg;

m2a=F+m2g-TT=F+m2g-m2a =150 + 510-520 =100 N
