2nd book top 30 mcq

A book sits on a horizontal top of a car which accelerates horizontally from rest. If the static coefficient of friction between car top and book is 0.45 , what is the maximum acceleration the car can have if the book does not slip ? (g = 10 ms^(-2))

You are reshelving books in a library. You lift a book from the floor to the top shelf. The kinetic energy of the book on the floor was zero and the kinetic energy of the book on the top shelf is zero, so no change occurs in the kinetic energy even though you did some work in lifting the books. Is the work-kinetic energy theorem violated?

The 2nd,31st and the last terms of an AP are 5 and -3 respectively. Find the AP and its 30th term.

A book is lying on the horizontal table top. If we tilt the table a little, then the book starts down slowly. This happens because :

The area of top face of a book, in the shape of a square, is 225 cm^(2) . The thickness of the book is 5 cm. Find its volume.

The cost price of 36 books is equal to the selling price of 30 books .The gain is:
