2023.24 Quest 3 Make up

Projectiles must have vertical and horizontal motions or components.  Using this information, which of the following scenarios WOULD BE defined as projectile motion: 

• a person diving straight down into a pool from a diving board
• a space shuttle orbiting the earth
• an apple falling from a tree
• a train moving along a flat track

Which of the following equations would you use to find the horizontal distance / range of a type II projectile? 

• Vcos(Θ) t
• horizontal velocity multiplied by time of flight
• the intial velocity multiplied by the cosine of the angle multiplied by the time of flight
• all answers are correct

vₓ is the symbol for horizontal ___________.

• velocity
• acceleration
• volume
• v for vendetta
