5. Projectile Motion

The cannon in FIGURE CP4.83 fires a projectile at launch angle θ with respect to the slope, which is at angle Φ. Find the launch angle that maximizes d. Hint: Choosing the proper coordinate system is essential. There are two options.

Which of the following statements about projectile motion with a horizontal launch is not true?

What happens to the vertical component of velocity as a projectile is launched horizontally and moves upward after launch?$v\_y$ (vertical component of velocity) as a projectile is launched horizontally and moves upward after launch?

In the figure, an electron is shot horizontally from the edge of a table with an initial speed of $v=2.0\times 106^{\mathrm{}}\text{ m/s}$. If the table is $1.2\text{ m}$ high, how far from the base of the table does the electron land? (Neglect air resistance and assume $g=9.8\text{ m/s}{2}^{}$.)

For an object launched horizontally in projectile motion (neglecting air resistance), is $\mathrm{mechanical} \mathrm{energy}$ conserved during its flight?

Which arrow best represents the path of an object launched horizontally from a height, neglecting air resistance?

In the context of a projectile launched horizontally from a certain height, which of the following best describes the trajectory of the projectile?

When a yo-yo is released horizontally from a certain height, what best describes the path it follows as it moves through the air?

If you throw a baseball straight up, which of the following statements about its motion is correct?

Which of the following statements about projectile motion with a horizontal launch is not true?

Which of the following statements is NOT valid for a projectile launched horizontally from a height, taking $u>0$ as positive?

Which of the following is an example of projectile motion?

In a horizontal projectile motion experiment, a ball is launched horizontally from a table and swings on a string attached to the ceiling. What is the angle that the string makes with the vertical at the highest point of the ball's travel, in $degrees$?

Which of the following quantities are constant during projectile motion?
