Centripetal acceleration is given by the formula

a_{cen}= \frac{v^2}{r}

Since we know the value of the acceleration is 9.8 m/s² and we know r, we can solve for the speed, which is the magnitude of v.  Note the value of a is just the acceleration due to gravity, which is what makes the rocket orbit and not fly off into space.

9.8 \frac{m}{s^2}=\frac{v^2}{6.381 \times 10^6m}   \\  \\ 9.8 \frac{m}{s^2} \times 6.381 \times 10^6m=v^2 \\  \\ v= \sqrt{9.8 \frac{m}{s^2} \times 6.381 \times 10^6m} =24755 \frac{m}{s}

What direction does centripetal acceleration point?
Nesterboy [21]

Answer:

Inward

Explanation:

As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced. hope this helps :)
