Overload

Calculate how many g's (gravity accelerations) feel glider pilot when turning the horizontal circles of radius 148 m flying at 95 km/h. Centripetal acceleration is proportional to the square of the speed and inversely proportional to the radius of rotation.

Consider a vertically acting gravity acceleration g=9.81 ms-1.

Correct result:

x =  1.11 g

Solution:

 aC=v2r=4.705 m/s2 x=ag a2=g2+aC2 x=g2+aC2g x=9.812+(26.3892148)29.81  x=1.11 g
