(b) Use the horizontal motion to find the time in the air. The grasshopper travels horizontally gives Find the vertical displacement of the grasshopper at The height of the cliff is 4.66 m. 3.23. Set Up: Let be upward. Solve: (a) gives and (b) At the highest point and At all points in the motion, downward. (c) Find when and Reflect: The acceleration is the same at all points of the motion. It takes the water to reach its maximum height. When the water reaches the building it has passed its maximum height and its vertical component of velocity is downward. 3.24. Set Up: Example 3.5 derives Solve: The maximum range occurs when and 3.25. Set Up: Example 3.5 gives and Solve: (a) R is a maximum when (b) (c) 3.26.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
