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