A physics textbook is placed on an inclined slope with an adjustable angle a. Thecoefficients of friction between the book and the slope are us = 0.5 and uk = 0.35respectively.1ma (i) Initially the book is not moving. Copy the diagram and draw all the forces acting onthe book. Show mathematical expressions for the size (magnitude) of each force. Ifwe slowly increase the angle a, at what angle does the book start sliding?(ii) Use the Work-Energy theorem to find a formula (expression) for the speed v ofthe book when it reaches the bottom, in terms of the angle a.(iii) If we place a ball of the same mass and material as that of book at the top, whatis the kinetic energy of the ball in terms of its mass and speed when it is rolling downthe ramp? Does friction (either static or kinetic) do any work on the rolling ball?Explain your answer.(Hint: the ball is a thin spherical shell)(iv) We release the book and ball at the same time, and record which reaches thebottom first. Which one wins? Is this true for all angles a?(v) What happens to the objects as a becomes nearly 90°?

Zoologists have studied the mechanics of locust jumping. When a locust jumps, as depicted in the figure, the resultant force R exerted by the hind legs is the sum of two forces. The first force W acts directly downward to support the locust's weight, which is about 0.02 newton. The second force F is for the takeoff; its magnitude is about 0.29 newton, and the direction makes an angle of 55° with the horizontal. W 55° Find the magnitude of the resultant force R = F + W. (Use decimal notation. Give your answer to three decimal places.) magnitude of resultant force R: newton
