WHAT IS THE RADIUS OF THE CURVE?
2007-08-17 13:15:57 · update #1
F=m*v*v/R
R=m*v*v/F
m=1200 kg
v=20 m/s
1 N= 1 Kg-m/(s*s)
m*V*V/F= 1200*20*20/6000=80
check the units
kg*m*m/(s*s)/(kg-m/s*s) = m
80m

F = (mv^2)/r
6000 = (1200*400)/r
r = 80meters
F = Centripetal force
v = velocity
m = mass
r = radius of the curve

r = mv^2/F
r = (1200)(20^2)/6000
r = 80 m.
