Explanation:
It is given that,
Speed of the plane, v = 110 m/s
Radius of circle, r = 2850 m
(1) Let t is the time taken by a plane. Speed of the plane is given by :
t = 162.79 s
(2) Mass of a driver, m = 50 kg
Height, h = 6 m
As the driver reaches ground, its potential energy point to zero. So, the change in potential energy is given by :
So, the change in potential energy is 2940 joules.
Let v is the speed. As the driver reaches water surface, its potential energy is converted to kinetic energy as :
v = 10.84 m/s
So, the speed of the reactors the water is 10.84 m/s. Hence, this is the required solution.
