what is the frictional force produced by the road of a force of 20 N is given to block of mass 2 kgbproduces an acceleration of 5 ms |

Answer» Answer: FRICTIONAL force produced by the road = 10N Explanation: ACCORDING to Newton's 2nd LAW of motion, UNBALANCED forces = ma Where m=mass of the body And a=accelration So here, unbalanced force is external force,F - frictional force,f = ma
20 - f = ma 20 - 2*10 = f Therefore, f =10N |
