An aircraft executes a horizontal loop of radius 1 km with a steady speed of 900 km h-1.Compare its centripetal acceleration with the acceleration due to gravity.

Asked by Abhisek | 1 year ago |  76

##### Solution :-

Radius of the loop, r = 1 km = 1000 m

Speed, v = 900 km h-1 =$$900 \times \dfrac{5}{18}$$= 250 ms-1

Centripetal acceleration: $$a_{c} = \dfrac{v^{2}}{r}$$

=$$\dfrac{\left (250 \right )^{2}}{1000}$$ = 62.5 ms-2

Acceleration due to gravity, g = 9.8 ms-2

$$\dfrac{a_{c}}{g} = \dfrac{62.5}{9.8}$$ = 6.38

$$a_{c}= 6.38 \; g$$
