Respuesta :
v = 25.0 km/h = 25*5/18 m/s = 6.94 m/s
centripetal force = mv²/r = 1275*6.94²/40 = 1537.18 N
centripetal force = mv²/r = 1275*6.94²/40 = 1537.18 N
The Centripetal force needed will be : 1535.215 N
What is centripetal force ?
Centripetal force is a force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.
centripetal force = m * [tex]v^{2}[/tex] / r
mass = 1275 kg
radius = 40.0 m
speed = 25.0 km/h = 25 * (5/18) m/s = 6.944 m/s
Centripetal force = 1275 * [tex](6.94)^{2}[/tex] / 40 = 1535.215 N
