2. (30 marks) A particle with a mass of $m$ is doing a circular motion with a constant speed of $v$ on an inclined smooth surface (neglect friction). The radius of the circle is $r$. Derive the inclination angle $\theta$, which allows the particle to maintain this uniform circular motion.

(c) (i) Give the definition of the Heaviside function $H(x)$. (ii) Show that $H'(x) = \delta(x)$, where $\delta(x)$ is the Dirac delta function. (iii) Compute the following integrals $\int_1^x \sqrt{t}H(t) dt$ $\int_{-\infty}^x \sin(\frac{\pi}{2})\delta(t^2 - 9) dt$ where $x$ is a real number. Express your results in terms of the Heaviside function.
