Question

You are riding your bike around a curve at a speed of 4.00 m/s. If the radius of the curve is 12.0 m, your centripetal acceleration is _____ towards the centre of the curve.

Answer 1

\[\large F_c = ma_c = \frac{mv^2}{r}\]

so plug in your values and solve for F

Answer 2

Sorry I realize me deriving it from the centripetal force equation might confuse you\[\large a_c = \frac{v^2}{r}\]

Plug in your 4 for 'v' and 12 for 'r'
