d) With what force must Hampus put on the top book from the side in order for it to slide off the other books if the coefficient of friction between the books is p=0.15? e) With what force must he put on the middle book in order for the top two books to slide off the bottom one? f) How big must the friction force between the table and the bottom book be?
Lasy three ( d, e, f)
Hampus has placed three physics books (Heureka!) on top of each other on a table. The books weigh 0.85 kg each.
a) Expose the bottom book and draw in all the forces acting on it with correct relative magnitudes.
b) Determine the compressive force on the table from the books.
c) Determine the pressure on the table from the books if they have sides 24 cm and 19 cm.
d) With what force must Hampus put on the top book from the side in order for it to slide off the other books if the coefficient of friction between the books is p=0.15?
e) With what force must he put on the middle book in order for the top two books to slide off the bottom one?
f) How big must the friction force between the table and the bottom book be?
