calculus please help me
find derivative of: f(x)=e^2 I know that b/c e is a constant the answer is 0, but how do I show that in my work?
physics
To plot the potential energy, simply plug your givens into the equation U=(1/2)kx^2. You should get a parabola that goes to 0 in the center. To determine the turning points of the block, use the law of conservation of energy. You know that Ui+Ki = Uf+Kf since there is no frict...
