To complete:The given problem so that it can use the concept of power.

Explanation of Solution
Introduction:
Power is the amount of work done or energy transferred per unit time. Also, work done is the product of force and displacement. SI unit of power is Watt and SI unit of work is J.
The given incomplete statement is that, person O is moving a 50 kg sofa while rearranging the furniture. So, to solve the problem using power, the following statement can be added.
“While rearranging furniture, person O needs to move 50 kg sofa 10 cm away from the original position in 5 minutes. Calculate the power consumed”.

It then hits a stationary block B (1kg) which then slides to a maximum distanced before it stops. Determine the value of d.The coefficient of static friction between theblock and the plane is μk = 0.2. The coefficientof restitution between A and B is e = 0.8.Ans: d=1.0034 marrow_forwardFigure 29-43 Problem 12. ••13 In Fig. 29-44, point P₁ is at distance R = 13.1 cm on the perpendicular bisector of a straight wire of length L = 18.0 cm carrying current i = 58.2 mA.
