Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_207

2/207 A projectile is fired with the given initial conditions. Plot the $r$- and $\theta$-components of velocity and acceleration as functions of time for the time period during which the particle is in the air. State the value for each component at time $t = 9$ s. Given: $v_0 = 120 \text{ m/s}$ and initial launch angle $\alpha = 55^\circ$ with the horizontal.
