80 meters. Since the only force on the car is centripetal force then:Fc = macac = v2/rFc = (mv2)/rSolve for rr = (mv2)/Fcr = (1200)(20)2/(6000)r = 80m(See my work in the link below.)
Fc = mV^2/r (2000 kg)(25 m/s)^2/(80 m) = 15625 Newtons
On earth 62.0 kilograms is 607.6 newtons or 136lbs 11oz
Weight in Newtons Mass in kilograms
Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2The centripetal acceleration doesn't depend on the stone's mass.(The centripetal force does.)The centripetal acceleration doesn't "act on" the stone.(The centripetal force does.)The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.

Force (newtons) = mass (kg) * acceleration ((m/s)/s) but > acceleration in a circle = velocity 2 / radius So > (centripetal) force = mass * (velocity 2 / radius)
100 newtons = 10.2 kilograms
only Newtons
Fc = mV^2/r (2000 kg)(25 m/s)^2/(80 m) = 15625 Newtons
One is that the centripetal force (f) created by the rotating mass (m) at a radius (r) can be calculated if the velocity (v) is known. . f (newtons)= m * (v2 / r)
There are 9806.65002864 Newtons in 1000 kilograms. Hope this helps!
Multiply mass in kilograms by 9.81 to get weight in Newtons
The mass of 19.6 Newtons is 1.99 kilograms at the earth's surface.
On earth, a mass of 2.26 kilograms weighs 22.15 newtons. (rounded)
45 newtons is about 4.6kg
On earth, 1kg is 9.8 newtons.
