I am working on homework but i cannot figure out what is wrong
1 view (last 30 days)
F = kx where F is the force in newtons and k is the spring constant in newtons per meter. The potential energy stored in the compressed spring is gived by E = 1 2 kx2 where E is the energy in joules. Plot energy E as a function of x (x ∈ [0, 10]) for two different spring constants k = 20N/m, 40N/m . Requirements are as follows: 1. Use different lines and markers for different k values(5 points). 2. Have labels on both axes (4 points), legends for different k values (4 points). 3. Use proper font size, line width and marker size (4 points). 4. In the PDF document, have a caption describing the figure (3 points) ------R2016b-----
x = [0: 1: 10];
k = [20 40];
F = k.* x
E = 0.5*k.*x.^2
I know how to plot and do other following things.
But i have no idea how to make this right

whenever you do array multiplication the no of elements in both array must be same or multiply with a constt number with array or matrix. this is the error is here but i can't give you exact answer you this question is the part of your homework .so i suggest you that make two case for the two value of spring constant.
in first case take value of k=20; than after do array multiplication it is the simply constt multiplication in to matrix
and soon on. i hope this will help you
