r(t) = (6+2 - 6t)i + (t + 3)j+k; to= 2 O x = 12 + 18t, y = 5 + t, z = 0 O x = 18t, y = t, z = t O x = 12 + 18t, y = 5 + t, z = 1 O x = 12 + t, y = t, z= t Question 4 2 pts Solve the problem. Unless stated otherwise, assume that the projectile flight is ideal, that the launch angle is measured from the horizontal, and that the projectile is launched from the origin over a horizontal surface An ideal projectile is launched from level ground at a launch angle of 260 and an initial speed of 48 m/sec. How far away from the launch point does the projectile hit the ground? O = 185 m O = 290 m O = 230 m O = 60 m Question 5 2 pts II Proctorio is sharing your screen.
