Numerically integrate and plot the response of an underdamped system determined by m = 100 kg, k = 20,000 N>m, and c = 200 , subject to the initial conditions of x0 = 0.01 m and v0 = 0.1 m>s, and the applied force F(t) = 150 cos 5t. Then plot the exact response as computed by equation (2.33). Compare the plot of the exact solution to the numerical simulation.
Equation 2.33- (ω2As + 2ζωπωBs + ωπ2As - f0)cosωt + (-ω2Bs - 2ζωπωAs + ωπ2Bs)sinωt = 0.
The car travels at a constant speed of 25 m/s makes a turn on a semi-circular curve. If it takes 20s to make the semi-circular turn, determine the magnitude of the car’s acceleration during the turn.
