80 meters. Since the only force on the car is centripetal force then:
Fc = mac
ac = v2/r
Fc = (mv2)/r
Solve for r
r = (mv2)/Fc
r = (1200)(20)2/(6000)
r = 80m
(See my work in the link below.)
32meters
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.
32meters
Force (newtons) = mass (kg) * acceleration ((m/s)/s) but > acceleration in a circle = velocity 2 / radius So > (centripetal) force = mass * (velocity 2 / radius)
only Newtons
100 newtons = 10.2 kilograms
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)
Multiply mass in kilograms by 9.81 to get weight in Newtons
There are 9806.65002864 Newtons in 1000 kilograms. Hope this helps!
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.
