The gravitational force between mars and an object near its surface is so much lower than the force between an object on earths surface and earth. If a dropped hammers speed increase from 0.0 m/s to 7.5 m/s in 2 seconds, what is the acceleration due to gravitational force on the surface of Mars?

Aspring is used to stop a 50-kg package which is moving down a 20ΒΊ 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.
