The first man-made satellite, sputnik 1, was launched into space in 1957. this satellite was used to study the conditions found in the higher atmospheric layers.
since then, other uses for satellites have been developed. one of these uses, satellite imagery, has made it possible to capture pictures of objects in space or on the earth. the advances that created satellite imagery have led to being able to
a.
homes and neighborhoods.
b.
planets and moons.
c.
types of landforms.

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.
