Question 17***If \(a_x=4\,\mathrm{m\,s^{-2}}\) and \(v_x(2)=10\,\mathrm{m\,s^{-1}}\), find \(v_x(t)\).
Question 18***+For \(v_x(t)=t^2\), find displacement from \(t=1\,\mathrm{s}\) to \(t=3\,\mathrm{s}\).
Question 19***+Starting with \(a_y=-g\), integrate to get the free-fall velocity and position equations.
Question 21****A particle has \(a_x(t)=6t-4\), \(v_x(0)=3\,\mathrm{m\,s^{-1}}\), and \(x(0)=-2\,\mathrm{m}\). Find \(v_x(t)\) and \(x(t)\).
Question 22****A particle has \(v_x(t)=t^2-4t+3\). Find its displacement and distance traveled from \(t=0\) to \(t=4\,\mathrm{s}\).
