Assume the entire mass of a 10 kg wheel along its rim which is 50 cm from the axis of rotation (the wheel is considered a thin ring). The wheel is rotating at an angular speed of 20 rad/s. If the wheel is braked through the brake pads on the edge and stops 1 second later, the force exerted by the brake pads on the wheel is equal to​

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
