I will check the spring constant again no problem, but the first part how to solve it ? Can you give me a hint ? Cuz I am so confused now if all this calculations is for nothing :(
1. Homework Statement
m = 4.00 kg
theta = 30
v = 1 m/s
compression of the spring by the block , x = 0.3 m
d = 5 m
Homework Equations
rule : Fk = μ k * N
i must find Fk first to find μ k using conservation energy, [/B]
The Attempt at a Solution
First find N,
N = m x g x cos theta
N = 4 *...
