A block of mass 1.5 kg is attached to a horizontal spring that has a force constant of 1.70 103 N/m, and is free to slide on a frictionless surface as shown. The spring is compressed to xi = −9.5 cm by pushing on the block, and then the block is released. Find the work done by initially compressing the spring? Find the kinetic energy of the block when it reaches x = 0? Find the speed of the block...

A massless spring is lying on a frictionless horizontal table. It has a spring constant of 800 N/m with an unstretched length of 23 cm and a 3 kg block is attached to its free end. You stretch the spring to a length of 33 cm and release it from rest. a) How fast is the block moving when the length of the spring is 28 cm? (Use ? = ?2 − ?1.)
A spring with a spring constant of 1500 N/m is attached to a block of mass...
A spring with a spring constant of 1500 N/m is attached to a block of mass 40 kg. If the spring is used to slide the block horizontally across a surface with a static coefficient of friction of 0.6 and a kinetic coefficient of 0.4, how much with the spring stretch before the block begins to move? How much will it stretch if the block is moving at a constant speed?

A 14 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 5.7 kN/m. The block is pulled to the right so that the spring is stretched 15 cm beyond its relaxed length, and the block is then released from rest. The frictional force between the sliding block and the surface has a magnitude of 44 N. (a) What is the kinetic energy of the block when it has moved 3.0 cm from...
A block of mass 1.8 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below
A block of mass 1.8 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. (a) A constant friction force of 3.4 N retards the block's motion from the moment it is released. How much is the spring compressed when the speed of the block is a maximum. (b) What is the maximum speed?
