5. Projectile Motion

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

A ball is launched horizontally from the top of a cliff with an initial speed of $v_0$. Which of the following statements correctly describes the motion of the ball immediately after it is launched?

When an object is launched horizontally and undergoes projectile motion (neglecting air resistance), which path does it follow?

A bungee jumper launches herself horizontally off a bridge. Which statement best describes her motion immediately after the jump, before the cord stretches?

Which term best describes the path followed by objects that exhibit projectile motion when launched horizontally from a height?

In projectile motion with a horizontal launch, assuming a constant wind speed blowing horizontally, which of the following statements about the projectile's horizontal motion is correct?

A projectile is launched from ground level with an initial speed $v_0$ at an angle $\theta$ above the horizontal. Which of the following expressions gives the maximum height reached by the projectile (neglecting air resistance)?

A diver runs off a platform and leaps with an initial speed of $5.0m/s$ at a $15°$ angle above the horizontal. Which of the following correctly describes the initial vertical component of her velocity?

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

A football is kicked horizontally from the top of a cliff. Which of the following best describes the initial velocity components of the football immediately after it is kicked?

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?
