5. Projectile Motion

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?

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?

Which of the following quantities are constant during projectile motion?

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?

A rock is thrown horizontally with a speed of 20 m/s from the edge of a high cliff. It lands 80 m from the cliff's base. How tall is the cliff?

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?
