Abicycle wheel of radius 0.3 m rolls down a hill without slipping. its linear velocity increases constantly from 0 to 6 m/s in 2.7 s. what is its angular acceleration? answer in units of rad/s 2 .through what angle does the wheel turn in the 2.7 s? answer in units of rad. how many revolutions does it make? answer in units of rev.

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
