A backpack full of books weighing 50.0 N rests on a table in a physics laboratory classroom. A spring with a force constant of 130 N/m is attached to the backpack and pulled horizontally.
If the backpack begins to slide when the spring (k = 130 N/m ) stretches by 2.30 cm , what is the coefficient of static friction between the backpack and the table?

A block with mass M = 6.0 kg rests on a frictionless table and is attached by a horizontal spring (k = 130 N/m) to a all.
A block with mass M = 6.0 kg rests on a frictionless table and is attached by a horizontal spring (k = 130 N/m) to a all. A second block, of mass m = 1.25 kg, rests on top of M. The coefficient of static friction between the two blocks is 0.30. What is the maximum possible amplitude of oscillation such that m will not slip off M?

A sled weighing 60.0 N is pulled up a snowy hill inclined at 10 degrees to the horizontal at a constant speed so that the coefficient of kinetic friction between sled and snow is 0.070. A penguin weighing 70.0 N rides on the sled. If the coefficient of static friction between penguin and sled is 0.950, find a). the force of friction between the sled and the snow, b). the force of static friction between the penguin and the sled,...

A block of mass 300 g rests on a smooth horizontal table and can slide freely without any friction. The block is attached to a spring of spring constant 100 N/m, whose other end is fixed to a wall. The block is pushed horizontally till the spring compresses by 12 cm, and then the block is released from rest. (a) Determine the speed of the block as it crosses the equilibrium point of the spring (i.e, where the spring is...

A spring lies on a horizontal table, and the left end of the spring is attached to a wall. The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move. The mass of the box is 0.75 kg, and the spring has a...
A horizontal spring of spring constant 100 N/m is attached to a wall, and a block (A) of mass 5 kg. The block rests on a frictionless table.
3. A horizontal spring of spring constant 100 N/m is attached to a wall, and a block (A) of mass 5 kg. The block rests on a frictionless table. It oscillates with an amplitude of 10 cm. On top of the block rests a second block (B), held in place only by friction. (A) If block B slips, where is it most likely to do so: near the center of the spring's travel, or near the extremes? Why? (B) How...
