(c) and The final velocity of the ball has magnitude and is directed at below the horizontal. Reflect: The time for the ball to reach the floor is the same as if it had been dropped from a height of 0.750 m; the horizontal component of velocity has no effect on the vertical motion. 3.10. Set Up: The initial velocity of the bomb is the same as that of the helicopter. Take downward, so and Solve: (a) with gives (b) The bomb travels a horizontal distance (c) (d) Graphs of x versus t and of y versus t are given in Figure 3.10. Figure 3.10 (e) Because the airplane and the bomb always have the same x -component of velocity and position, the plane will be 300 m directly above the bomb at impact. 3.11. Set Up: Take to be downward. For each cricket, and For Milada, For Chirpy, Solve: Chirpy’s horizontal component of velocity has no effect on his vertical motion. He also reaches the ground in 3.50 s. Reflect: The x and y components of motion are totally separate and are connected only by the fact that the time is the same for both. 3.12. Set Up: Take downward. She must travel 1.75 m horizontally during the time she falls 9.00 m vertically.

### 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.
