A body of mass 60kg is pushed with just enough force to start it moving on a rough surface with us=0.5 and uk=0.4 and the force continues to act afterwards. The acceleration of the body is? Since us and uk are static as well as kinetic friction 1) 0.98. 2)3.92 |

Answer» eleration of the body is a = 1 m/s^2Explanation:The Uniting friction = μs R μs mg = 0.5 × 60 × 10 = 300 NKinetic friction = μk R = μ k mg = 0.4 x 60 x 10 = 240 NForce applied = 300 N Net ACCELERATING force = Applied force - kinetic frictionma = 300 - 240 = 60a = 60 / 60 = 1 m/s^2Thus the acceleration of the body is a = 1 m/s^2Also learn moreIf the mass of a MOVING object is 50 KG, what force will be required to SPEED up the object at a rate of 2 ms^-2 ? brainly.in/question/1146023 |
