The upper end of a light rope of length L = 0.600 m is attached to the ceiling, and a small steel ball with mass m= 0.200 kg is suspended from the lower end of the rope. Initially, the ball is at rest and the rope is vertical. Then a force F⃗→with constant magnitude F= 0.760 N and a direction that is maintained tangential to the path of the ball is applied and the ball moves in an arc of a circle of radius L. What is the speed of the ball when the rope makes an angle α= 37∘ with the vertical?

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.
