Suppose you drop an object from rest. after 1 s, it is traveling m/s. after 2 s, it is traveling m/s. after 3 s, it is traveling m/s. after 5 s, it is traveling m/s. after 10 s, it is traveling m/s.'

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.
