hey every1.. at the moment for a school project a group of mates and i are building a rat trap operated car. This is made by obviously a rat trap with about 5mm diamater front wheels and cds as the rear wheels... this is just a quick explanation. what i need to do is find out how far the car...
im confused at what ur asking for but here we go it might give u a start
F= Gm1m2/r^2
F=ma
m1a=Gm1m2/r^2
a=Gm2/r^2
v/t=Gm2/r^2
v=Gm2t/r^2
then use Speed = dist/time
is that what u wanted?
no idea if this is right but yeah...
T=(2*PI*r)/v
V=(2*Pi*r)/T
T=15min = 900sec
V=(2*pi*r)/900 _____(1)
Distance= speed*time
t=D/S _______________(2)
distance is the diamater which is 2r
equation 1 into 2
t=2r/((2*Pi*r)/900)
after abit of algebra
t=900/pi
t= 286.48...
