Question
***IMAGE IN ATTACHEMENT***
A block of mass 2 kg compresses spring 1 with a force constant, k1=10000 N/M, by 8 cm. It is released and slides for a total of 50 cm on a surface with μk=0.2, at which point it compresses another spring 2, k2=1000 N/M and momentarily comes to rest. Remember that Us is the potential energy of the spring. Find the following values:
What is the Initial spring potential energy of spring 1.
J
Tries 0/2 |
How much energy is dissipated by heat? This is the amount of work done by friction × -1.
J
Tries 0/2 |
How much Potential Energy does spring 2 have when the block has compressed spring 2 and is momentarily stopped?
J
