Two blocks of masses 5 kg and 2 kg are kept in contact with each other on a frictionless horizontal surface. If a force of 14 N is applied on the larger block what is the acceleration of the system ? What is the contact force between the two blocks ?

Text Solution

Verified by Experts

`M_(1)=5 kg , M_(2)=2 kg, F=14 N`.
(i) `a=(F)/(M_(1)+M_(2))=(14)/(5+2)=2ms^(-2)`
(ii) `f=(M_(2)F)/(M_(1)+M_(2))=((2)/(5+2))=14=4N`
