A
positive
3
Q
what is a projectile?
A
a projectile is an object, animate or inanimate, that is launched into motion and when in motion and is unaffected by any external forces other than gravity
4
Q
what will an objects CoG follow?
A
an objects CoG will follow a parabolic flight path
5
Q
what is the equation needed to determine time to smax (max height)?
A
t=v-u over a
6
Q
what is the equation to find smax (max height)?
A
s=1/2 Utime to smax
7
Q
why is time going up the same as time going down?
A
because gravity slows it down going up and increases speed when going down.
8
Q
how do you determine total flight time?
A
total flight time= tup+tdown
