Free Fall
definition of free fall
Definition: the motion of an object only affected by gravity
between a launch angle of 35 and a launch angle of 55, which of the two produces a greater range
none cus they complement each other or smth
negative
how to get total ME
KE + PE
7 horsepower = ___ kilowatts
5.14849 KW
probably cus googles always right
distance formula
1/2gt^2
why is there no y arrow in a thingymabob when the projetcile is at its vertex/highest point
no idea but like ill know it when i hear it <3
correct!
what does the work energy theorem state
W = KEf-KEi=KE
Sammys output work is 7 while christas is 2
the input work is 8 for both sammy and christa
who is more efficient
bonus: sammy does not eat any food of this color, what color
sammy obvi
green bleh
Which of the two will drop first if they are both dropped at the same time in ideal conditions?
1 page of my kumon worksheet
a bottle of lotion
kumon sheet
cus its flat
yehey!
how would u solve for the Viy using the launch angle and Vi
Visin0
i think?
Ginny pushes a box with a force of 441N! wow so strong ginny
both force and displacement have the same numerical value, so like what are they
<3
BONUS: does sammy prefer red sauce or white sauce pasta
21
white sauce
whats the KE if
m = 2
v = 76
Bonus: whats sammys fav color
5776J
yellow
whats the efficiency if
MA = 2
IMA = 3
correct!
whats the trend of the graph projected by acceleration due to gravity (g) vs the drop height of a falling object
like what kinda line yk
bonus: how old is sammys brother
straight line
31
__0=Vix/Viy
sin cos tan
bonus: what color is sammys bra right now
backup emergency bonus question: what language was sammy forced to learn in like pandemic
cos
im not wearing a bra sorry
backup emergency: chinese
true or false
Joules = kg x m^2/s
false
kg x m^2/s^2
a pendelum thing is launched from a height of 1m
its PE is 24.5J
at its lowest point, its KE is 26J
so like its max ke is 26 basically
why?
haha trick question
not possible
why is there never gonna be 100% efficiency
input work is lost through heat, friction, blah blah blah
100 is idea and we are not so yes
christa and my squishmallow are falling off a building like right now irl
which one hits the ground first
christa :(
Sammy hits a christa! Christa launches with a horizontal velocity of 22 m/s and a vertical velocity of 8 m/s. Calculate the launch angle and the initial speed.
angle: 19.98
Vi: 23.41
im like really lazy so
whats the force if work is 2 and displacement is 3
2/3
i dont wanna get my calculator
V=8m/s
mass?
70kg
ginny has a mass of 2kg and races christa at a speed of 3m/s
unfortunately, christa wins since she finished within 10 which was 5 less seconds than ginny
whats ginnys power
aslong as u did
(2 x 3^2)/15
