Wo balls, each with a mass of 0.838 kg, exert a gravitational force of 8.08 x 10-11 N
on each other.
How far apart are the balls? The value
of the universal gravitational constant is
6.673 x 10-11 N m²/kg?.
Answer in units of m.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

Awoman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. the book has a mass of m = 1.8 kg and the coefficient of static friction between her hand and the book is μs = 0.67. no attempt 50% part (a) what is the weight of the book, fgb in newtons?
