A pen contains a spring with a spring constant of 295 N/m. When the tip of the pen is in its retracted position, the spring is compressed 5.20 mm from its unstrained length. In order to push the tip out and lock it into its writing position, the spring must be compressed an additional 6.90 mm. How much work is done by the spring force to ready the pen for writing? Be sure to include the proper algebraic sign with your answer. Number Units

hysics.com/myct/itemView?assignment ProblemID=189028777 2 W S You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 13-m-high hill, then descends 19 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.5 m and that a loaded car will have a maximum mass of 450 kg. For safety reasons, the spring constant should be 15% larger than the minimum needed for the car to just make it over the top.

A pen contains a spring with a spring constant of 240 N/m. When the tip of the pen is in its retracted position, the spring is compressed 5.00 mm from its unstrained length. In order to push the tip out and lock it into its writing position, the spring must be compressed an additional 6.60 mm. How much work is done by the spring force to ready the pen for writing? Be sure to include the proper algebraic sign with your answer.

Answer parts a, and b of the following question.7. a) You want to store 1,000 J of energy in an ideal spring when it is compressed by only 2.5 cm. What should be the force constant (spring constant) of this spring? b) A very light ideal spring having a spring constant (force constant) of 8.2 N/cm is used to lift a 2.2-kg tool with an upward acceleration of 3.25 m/s2. If the spring has negligible length when it us not stretched, how long is it while it is pulling the tool upward?
A 10kg block is released from rest at point A the in figure shown. The track is frictionless except for the portion between points B and C, which has a length of 6m. The block travels down the track, hits a spring of force constant 2250N/m and compresses the spring 0.3m from its equilibrium position before coming to rest momentarily. You may assume that the spring has negligible mass. 3.00 m -6.00 m- B) (a) Let uk be the the coefficient of kinetic friction of the rough surface between point B and C.
