A wheel of radius 74 cm, mass 4 kg, and moment of inertia 1.0952 kg m2 are mounted on a frictionless, horizontal axle as shown. A light cord wrapped around the wheel supports an object of mass of 1.7 kg. Find the tension T in the cord. The acceleration due to gravity is 9.8 m/s^2 Answer in units of N.

What is the angular acceleration of the wheel?
Answer in units of rad/s^2

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
