certain physics problem about projectile motion has several parts, as listed in the questions below. For each, write out what variables (y, vy, ay, t, x, vx, etc) need to be solved for in each part, and at what event
A certain physics problem about projectile motion has several parts, as listed in the questions below. For each, write out what variables (y, vy, ay, t, x, vx, etc) need to be solved for in each part, and at what event or condition, also expressed using symbols and/or known values. For example: “Find ______ (variable) when _______ (variable) equals ________.”
How long until the projectile hits the ground?
How far has the projectile travelled horizontally, when it hits the ground?
What is the projectile’s speed the moment before ithits the ground?
What is the projectile’s direction (angle) of flight, just before hitting the ground?
How long until the projectile reaches its maximum altitude?
What is that maximum altitude?
How long until the projectile reaches a wall/building standing 100 m away (horizontally)?
