A 5.6 kg bucket of water is raised from a well by a rope.
The acceleration of gravity is 9.81 m/s2.
If the upward acceleration of the bucket is
4.8 m/s?, find the force exerted by the rope
on the bucket of water.
Answer in units of N.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
