A)Find the velocity of a wheel that has a diameter of 2m and angular velocity of 5 rad/s. b) If the wheel has an angular acceleration of 3.0rad/s/s for 4 seconds then what is its final angular velocity and angular displacement?
Given: d=2m, ⍵o=5rad/s,=3.0rad/s2 ,Δt=4s

Unknown:v=?, b) ⍵f =? and Δϴ=?

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
