Find the maximum distance the spring will be compressed You are asked to design a spring that will give a 1310-kg satelite a speed of 3.00 m/s relative to an orbiting space shuttle. Your spring is to give the satelite a spring's mass, the recol kinetic energy of the shuttle, and changes in gravitational potential energy will all be negligble. of 5.00g. The 2 5 8 9 A/

Explanation / Answer

Potential energy = 1/2* kx^2 = 3.24 J

x^2 = 3.24/ (0.5*1552)

x = 0.004175 m

D = total distance  

P.E (lost) = mgD = 1.16*9.8D = 11.368*D J

P.E gained by the spring = 1/2kx^2 = 776*x^2 J

776*x^2 = 11.368*D

D =( 0.79 + x)

776*x^2 = 11.368*( 0.79 + x)

x = 0.4134 m
