# Question

(a) How many uniform, identical textbooks of width 25.0 cm can be stacked on top of each other on a level surface without the stack falling over if each successive book is displaced 3.00 cm in width relative to the book below it?

(b) If the books are 5.00 cm thick, what will be the height of the center of mass of the stack above the level surface?

(b) If the books are 5.00 cm thick, what will be the height of the center of mass of the stack above the level surface?

A 10.0-kg solid uniform cube with 0.500-m sides rests on a level surface. What is the minimum amount of work necessary to put the cube into an unstable equilibrium position? A force is applied to a cord wrapped around a solid 2.0-kg cylinder as shown in Fig. 8.45. Assuming the cylinder rolls without slipping, what is the force of friction acting on the cylinder? Two objects of different masses are joined by a light rod. (a) Is the moment of inertia about the center of mass the minimum or the maximum? Why? (b) If the two masses are 3.0 kg and 5.0 kg and the length of the rod is 2.0 ...A planetary space probe is in the shape of a cylinder. To protect it from heat on one side (from the Sun’s rays), operators on the Earth put it into a “barbecue mode,” that is, they set it rotating about its long axis. ...Estimate the ratio of the translational kinetic energy of the Earth as it orbits the Sun to the rotational kinetic energy it has about its N– S axis.Post your question
