Answer:
U = tantheta - KX/mgcostheta
Step-by-step explanation:
The formula for calculating the coefficient is given by.
KX = mgsintheta - mgucostheta
Making u subject of the formula we have
U = tantheta - KX/mgcostheta
K = 165N/m
X = 12 cm = 0.12m
U = tantheta - 165*0.12/mg*costheta
The question isn't complete but with this you can fix value for the mass and angle to get the final answer easily
