Find the centripetal force needed to keep an 60.0 kg rider traveling in a circle in the ride. Given:
m=
V = (from part a)
R =
Unknown:
F=?
Equation:
F= m (y^2) / r

Explanation:

Given that,

Mass of the rider, m = 60 kg

Let the radius of the circle, r = 30 cm = 0.3 m

Let the velocity, v = 20 m/s

We need to find the centripetal force needed to keep the rider in a circular path. It can be given by :

So, the required force is .

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
