hi, i need answers on the questions below. please provide explanation or solution if needed so i can better understand it. thank youu!

FOR ITEM 5, 6, AND 7 A physics book slides off a horizontal tabletop with a speed of 1.10 m/s. It strikes the floor in 0.350 s. Ignore air resistance. 6 Find the height of the tabletop above the floor; (b) the horizontal distance from the edge of the table to the point where the book strikes the floor A. -0.200 m B. -0.400 m C. -0.600 m D. -0.800 m E. No Answer7. Find the horizontal distance from the edge of the table to the point where the book strikes the floor A. 0.265 m B. 0.385 m C. 0.498 m D. 0.597 m E. No Answer 8. Find the horizontal and vertical components of the book's velocity, and the magnitude and direction of its velocity, just before the book reaches the floor. A. -3.43 m/s B. -5.69 m/s C. -7.56 m/s D. -9.45 m/s E. No AnswerFOR ITEM 8 AND 9 The earth has a radius of 6380 km and turns around once on its axis in 24 h. 8. What is the radial acceleration of an object at the earth's equator? Give your answer in m/s^2 and as a fraction of g. (g = -9.8 m/s^2) A. 1.8x10^-3 g B. 2.6x10^-3 g C. 3.4x10^-3 g D. 4.1x101-3 g E. No Answer 9. If the radial acceleration at the equator is greater than g, objects will fly off the earth's surface and into space. What would the period of the earth's rotation have to be for this to occur? (g = -9.8 m/s^2) A. 0.27 hrs. B. 0.45 hrs. C. 0.94 hrs. D. 1.4 hrs. E. No
