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 .

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
