Question

An aeroplane travelling at a speed of 500kmph tilts at an angle of 30° as it makes a turn. What is the radius of the curve

Answer 1

velocity of the plane (v)=500kmph=139 mps.Angle at which it made the turn(x) = 30°Let' s take acceleration due to gravity(g) to be 9.8mps^-2.Then ,Using the formula,v^2/rg = tanx.where r= radius of the loop.Putting the values weget19321/9.8r=0.57r= 19321/9.8×0.57r=3458.8 metres.Or ,the radius of the loop executed by the plane is 3.45 km.
