Question #b4e13

Answer 1

`2 m/s^2`

Explanation:

For uniform circular motion the acceleration (`a`) can be calculated as a function of the velocity (`v`) and the radius (`r`).
`a = v^2/r`
The mass of the object is not needed in this calculation.
`a = (1m/s)^2/(0.5m)`
`a = 2 m/s^2`

If you wanted to calculate the force required to maintain this motion, then you only need to know that `F = ma`. This mass in this case is `0.010 kg`.
`F = 0.010 * 2 = 0.02 N`
