Consider the force-displacement graph for a spring shown. Determine the spring constant, the potential energy stored when the spring is stretched from x = 0 to x = 4.0 cm. the change in the potential energy stored in stretching the spring from x = 1.0 cm to x = 4.0 cm. A cart having a mass M = 180 g on a friction free horizontal surface is accelerated from rest by the launching spring of problem 2. What is the...
A spring with a force constant k = 2.2x10^2 N/m is stretched by a person. The person pulls on the spring with a final applied force of F_app = 44 N at equilibrium (no motion). How much work was done by the person in the process? A spring with a force constant k = 2.2x10^2 N/m is stretched by a person. The person pulls on the spring with a final applied force of F_app = 44 N at equilibrium (no...
A spring has a force constant of k 104 N/m. (a) How far must it be stretched for its potential energy to be 70 J? (b) How far must it be stretched for its potential energy to be 140 J?
A pen contains a spring with a spring constant of 300 N/m. When the tip of the pen is in its retracted position, the spring is compressed 5.30 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 7.00 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...
A spring has a force constant of k 1.0 x 104 N/m. (a) How far must it be stretched for its potential energy to be 80 17 (b) How far must It be stretched for Its potentlal energy to be 160 J? eBook
