Unformatted text preview: 77. To get the time to reach the maximum height, we use Eq. 423, setting the lefthand side to zero. Thus, we find (60 m/s)sin(20o) = 2.094 s. t= 9.8 m/s2 Then (assuming α = 0) Eq. 1013 gives θ − θo = ωo t = (90 rad/s)(2.094 s) = 188 rad,
which is equivalent to roughly 30 rev. ...
