Answer Part 2 plz, I posted the part 1 somewhere else. I know the policy is only one question per post so I posted the problem separately.

Part II (1.5 points): Instability of EM Turn off the sliding friction and set h = 0.1, but keep all other parameters the same. Integrate using the Euler Method. You will see that the oscillator is now unstable. As one shrinks h, the oscillations become more convergent to steady state, however, ideal behavior (y(t) = y(t + T), where T is the period of the oscillation) requires infinite numerical precision. Show what the behavior looks like with the IEM and the RK4 method for h = 0.1 [DLV x 2] Find the limit of h for the Euler Method (EM) such that the oscillations increase by less than 1% over a period of 1 oscillation, i.e., y(t + T)
