An r=4.5 cm soccerball is released from rest at the top of ahill and takes t=3 s to get to the bottom. What is the final linearvelocity if α=2 rad/s2?
An r=4.5 cm soccerball is kicked at ωi=1.1 rad/s from the top ofa hill and takes t=1.5 s to get to the bottom without loosingcontact with the ground. Find how many revolutions does thesoccerball make if α=2 rad/s2?
A bicycle wheel rotating at ωi=33.2 m/s brakes with an angularacceleration of magnitude α=0.4 rad/s2 for t=8s. How manyrevolutions did it make before stopping?
A toy plane’s propeller takes off from rest with an accelerationof α(t)=2.3t 2 rad/s2 . How many rotations has it made after t=6s?
A windmill turning at ωi=0.1 rad/s experiences sever wind fort=80 s that cause an acceleration of α(t)=0.2t 3 rad/s2 . How manyrevolutions does it make in the 80 s?
