Figure 1The diagram above (Figure 1) shows the situation forthe three questions below (questions 1, 2, and 3). Thenumbers will change in each question but the situationis the same. Adam is pushing a cart which rolls on thefloor with negligible friction. There is a book on top ofthe cart. The book moves with the cart (the book doesnot slide on the surface of the cart). This question also refers to the situation in Figure 1.There is no friction between the cart and the floor. Thebook moves with the cart with no sliding between thebook and the surface of the cart. The cart has a mass of12.7 kilograms and the book has a mass of 2.28kilograms.The coefficient of static friction between the book andthe cart is 0.42. The coefficient of kinetic frictionbetween the book and the cart is 0.21.As Adam pushes the cart for a distance d; of 2.8meters, the cart accelerates to the right with a constantacceleration of 1.2 meters per second squared. For thepurposes of this problem, the acceleration of objects infreefall is g = 9.81 m/s?.Calculate the work in joules that Adam (only Adam) didon the cart (only the cart) as it moved to the right adistance di meters. The sign (positive or negative) isimportant.
