Question

a body of mass 20kg kept intialy at rest . a force of 80N applied on the body then the acceleration produced in the body is 3m/s^2 force of friction act on the body is​

Answer 1

Heya......!!!

________________________

Given in The question :-

• Mass of Body = 20 Kg

• Acceleration = 3 m/s^2

• Force = 80 N

If we calculate the force from this information then F' = 20 × 3 = 60 N . ( force which accelerated the body )

But the given force is 80 N .

Then the Frictional Force acting on the body is

Fr = F' - F = 80 - 60 = 20 N

Frictional Force => 20 N .
