A ball is dropped and falls

A0.5-kg object is connected to a spring that undergoes oscillatory motion. there is friction between the object and the surface it is kept on given by coefficient of friction μk = 0.06 . if the object is released 0.2 m from equilibrium, what is the distance that the object travels? given that the force constant of the spring is 50 n m-1 and the frictional force between the objects is 0.294 n.

Two objects, =15.3 kg and =5.31 kg are connected with an ideal string and suspended by a pulley (which rotates with no friction) in the shape of a uniform disk with radius =7.5 cm and mass =14.1 kg. the string causes the pulley to rotate without slipping. if the masses are started from rest and allowed to move 2.5 m:

Acustomer currently has a desktop pc which, among other things, has a 970 gaming atx am3 motherboard, with a pata hard drive that has 150 gb storage and 3600 rpm spindle speed. the customer is complaining that the pata hard drive is running out of storage and is slow. they indicate that they have a budget of $200 and would like this hard drive to last for the next few years. they have several videos and photos that they currently need to store, which will take up at least 100 gb. they anticipate the need to store at least 75 gb of data over the next few years.
