A pilot of mass m can bear a maximum apparent weight 7 times of mg.The aeroplane is moving in vertical circle.if the velocity of aeroplane is 210m/s while diving up from the lowest point of vertical circle, the minimum radius of vertical circle should be

Ans:750m

1 answer

m v^2/r + m g = 7 m g

v^2/r = 6 g

r = (210)^2/(6*9.81)

r = 749 meters
