Question 239

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A ball is projected from a point O O\,O on horizontal ground with speed U U\,U m s−1^{-1}−1 at an angle θ \theta\,θ above the horizontal.

A vertical wall of height 6 m stands on the same horizontal ground, 20 m from OOO, in the vertical plane of the ball's motion. The ball just passes over the top of the wall.

The ball lands on the ground 32 m from OOO.

Figure for question 5

Find the value of θ \theta\,θ and the value of UUU.
