A block of mass m = 0.36 kg is set against a spring with a spring constant of k1 = 625 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 335 N/m.
a)How far, d2 in meters, will the second spring compress when the block runs into it?
b) How fast, v in m/s, will the block be moving when it strikes the second spring?

Question

A block of mass m = 0.36 kg is set against a spring with a spring constant of k1 = 625 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 335 N/m. 
a)How far, d2 in meters, will the second spring compress when the block runs into it?
b) How fast, v in m/s, will the block be moving when it strikes the second spring?

anonymous · Answer

Now assume friction is present on the surface in between the ends of the springs at their equilibrium lengths, and the coefficient of kinetic friction is μk = 0.5. If the distance between the springs is x = 1 m, how far, d2 in meters, will the second spring now compress?
