Cory is riding his bicycle directly east. In 2.0 minutes, he covers 1100 meters of distance. What is
his velocity?
a. 11 m/s
b. 9.2 m/s
c. 550 m/s
d. -9.2 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.
