True

False

Sometimes true

Sometimes false

less than if it was just dropped

the same amount of time than if it was just dropped

impossible to determine

When a ball is projected horizontally, what is its initial vertical velocity?

not enough information given

0.52 s

0.27 s

0.13 s

0.36 s

10.

A bullet is fired horizontally at a height of 1.3 meters at a velocity of 950 m/s. Assume no air resistance. How far did the bullet travel horizontally when it hit the ground?

252.04 m

489.32 m

126.02 m

346.00 m

11.

Which of the following shapes is seen in the trajectory of a projectile?

straight line

parabola

circle

hyperbola

12.

The horizontal component of a projectile's velocity is independent of...

it's range

time

the vertical component

none of these

13.

A projectile is launched from a height with an initial horizontal velocity of 20 m/s. If the projectile flies for 40 seconds, what is its horizontal velocity just before it hits the ground?

20 m/s

2 m/s

800 m/s

2 m/s

14.

Four turkeys push a lawn mower traveling at 20 m/s horizontally from a cliff with a height of 15 meters. How far from the cliff will the lawn mower land if it hits the ground 1.7 seconds after it is launched?

Identify the variable you are being asked to find.

Δy

V_x

Δx

V_y

15.

As an object travels through the air, its vertical velocity

changes continuously

remains the same

16.

As an object travels through the air, its horizontal velocity

changes continuously

remains the same

17.

A plane drops a package for delivery. The plane is flying horizontally at a speed of 150m/s, and the package travels 300m horizontally during the drop.

How do you find the vertical displacement (the drop height)?

Find the time using V_x & dx; then Δy = ¹/₂gt²

Find the time using V & g; then Δy = ¹/₂gt²

Δy = ¹/₂gt²

Find the v_if using dx & g, then find dy using v_iy2 = v_if²+ 2 * g * Δy

18.

Which vector pair (arrow pair) correctly represents the acceleration and velocity at point P?

19.

Who do you agree with?

Anita: “A projectile’s v_xchanges because of gravity, and its v_yremains constant.”

Barry: “Both v_x and v_y are constant.”

Chris: “A projectile has no acceleration in the vertical dimension but it does accelerate horizontally.”

Dave: “A projectile has vertical acceleration and a constant horizontal velocity”

20.

A horizontally-launched projectile arcs out and hits the ground below. The vertical displacement and the horizontal displacement are measured. What is the best equation to use to find the time the projectile was in the air?

$\Delta\overrightarrow{x}=\overrightarrow{v}_x\cdot\Delta t$

$\Delta\overrightarrow{y}=\overrightarrow{v}_{yi}\cdot\Delta t+\frac{1}{2}\cdot g\cdot\Delta t^2$

$\overrightarrow{v}_{yf}=\overrightarrow{v}_{yi}+g\cdot\Delta t$

$\Delta t=\sqrt{\frac{2dy}{g}}$
