A box with mass 8 kg slides down a ramp that is inclined at an angle of 20 degrees. Draw a free body diagram. Consider the diagram below wherein an object (colored yellow) is being pushed upwards an inclined plane with an applied force. Explain why the force (mg -...
A body of mass 200 kg is dragged through a distance of 8m on a level ground. What is the work done, if the coefficient of friction is 0.25? View Solution Calculate work done to move a boy of mass 20 kg along an inclined plane (theta = 45^(@)) with constent velocity through a ...
In the first frame of that figure (far left) there is no force on the movable object and the bristles are straight. In the second frame, a small force is applied and the bristles begin to bend; here, the movable object moves a bit and stops. The force is proportional to ΔP, the ...
