What is the kinetic energy K of the rotating wheel? Express your answer in terms of m, r, n, t, and π.

K = ( (pi)^2 * n^2 * m * r^2 ) / t^2

Explanation:

=(1/2)Iw^2

I = moment of inertia= (1/2)mr^2

w = angular speed = 2(pi)n/t

By substitution, we have

K = ( (pi)^2 * n^2 * m * r^2 ) / t^2

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
