That box up there on that table has a mass of 10 kg. It is in contact with a spring that is compressed 5 cm from its equilibrium position. The spring has a stiffness constant of 1000 kg/s^2. There is no friction between the box and the table and the table is 1 meter high.

Once the spring is released it will push the box forward with its full extension at which point, the box will leave the surface of the table.

How far will the box go in the 'x' direction once it leaves the table, before it hits the floor?

A block with mass m = 14 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4399 N/m after being compressed a distance x1 = 0.468 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2 m long. For this rough path, the coefficient of friction is μk = 0.48. 1)How much work is done by the spring as it accelerates the...

A block of mass 0.25 kg is against a spring compressed at 0.20 m with spring constant 50 N/m. When the spring is released, the block moves along the frictionless surface until entering a region with the coefficient of kinetic friction equal to 0.30 (when the block enters the friction region it is no longer in contact with the spring ). How far,L,into the region with friction does the block slide before stopping?
