Question 138
In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.
A ball, modelled as a particle, is projected from a point O O\,O on horizontal ground with speed 20 m s−1^{-1}−1 at an angle of 40° 40°\,40° above the horizontal. Air resistance is modelled as negligible.
A vertical wall of height 5 m stands on the same horizontal ground, at a distance of 12 m from OOO, in the vertical plane of the ball's motion.
Determine whether the ball passes over the wall.
