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...

An 8 kg block and a 2 kg block are attached by a string as shown. A 40 N horizontal tension force pulls on the 8 kg block and the string connecting the blocks remains taut while they slide to the right. The surface below is horizontal and frictionless and the strings have negligible mass. Find the magnitude of the tension force that the 8 kg block pulls on the 2 kg block with (the tension in the connecting string).
A 280 g wood block is firmly attached to a very light horizontal spring, as shown in the figure
A 280 g wood block is firmly attached to a very light horizontal spring, as shown in the figure . The block can slide along a table where the coefficient of friction is 0.30. A force of 22 N compresses the spring 18 cm. If the spring is released from this position, how far beyond its equilibrium position will it stretch at its first maximum extension?
