Question

An object of mass 10 kg is in a circular orbit of radius 10 m at avelocity of 10 m/s. What is the acceleration of this object?a 0.01 m/s2b 1.0 m/s2C 10 m/s2d 100 m/s2

Answer 1

The acceleration formula is

`a=(v^2)/(r)`

Where v = 10 m/s and r = 10 m. Let's use these values to find the acceleration.

`\begin{gathered} a=((10\cdot(m)/(s))^2)/(10m)=(100\cdot(m^2)/(s^2))/(10m) \\ a=10\cdot(m)/(s^2) \end{gathered}`

Therefore, the answer is C.
