Evaluate \(\lim_{N \to \infty} \frac{1}{N} \sum_{j=1}^{N} \sqrt{19 - 19\left(\frac{j}{N}\right)^2}\) by interpreting it as the area of part of a familiar geometric figure. (Use symbolic notation and fractions where needed.) \(\lim_{N \to \infty} \frac{1}{N} \sum_{j=1}^{N} \sqrt{19 - 19\left(\frac{j}{N}\right)^2} = \)

of 1.00 m. A mass m = 1.50 kg is attached to a spring and oscillates on a frictionless surface with simple harmonic motion. The position of the mass as a function of time is given by: x(t) = 2.10 cos(1.06t+ 0.628) m. Part 1) What is the period of oscillation of the mass? Part 2) What is the acceleration of the mass at time t = 3.40 s? Take the positive x-direction to be to the right. Part 3) What are the potential and kinetic energies of the mass at time t = 3.40 s?
