Question

On a smooth horizontal surface two blocks of masses 5kg and 2kg are placed one upon other. A force of 10N is applied on the lower mass 5kg. What will be the acceleration of 5kg block in m/s^2 if coefficient of friction between the blocks is 0.1?

Answer 1

Answer:

Explanation:

acceleration if both move together = 10/7 m/sec^2

frictional force acting on them = 20/7 n

static frictional force = 5

you can see frictional force acting on them is less than static frictional force

so both bodies move together

acceleration of 5 kg block = 10/7 m/sec^2
