A book with the mass of 1 kg is sliding to the left on a table. if the frictional force on the book is 5 N , calculate the books acceleration. is it speeding up or slowing down

Explanation:

The force of friction always acts in opposite direction to the force applied for sliding the body .

If the applied force is F , the force of friction is 5 N .

Then the resultant force is ( F - 5 )

The acceleration =  net force / mass

Thus acceleration= ( F - 5 )/1 = F - 5

Therefore , the applied force decreases , by which the acceleration als decreases . By which the body will slow down .
