Answer 1

Answer #1

Area=theta=1/2*2*20 + 2*20 = 60rad
To determine the number of revolutions just divide this angular displacement by 2pi.
#rev=60rad/6.28rad/rev = 9.55rev

How many revolutions does the object make during the first 4 s?

In the Cartesian coordinates, a figure shows the angular-velocity versus time graph for a particle moving in a circle.y axis is the angular (rotational) speed (w) as "rad/second" and x axis is time (t) as "second".The motion is linear in the first two seconds as:10 rad/s at t=120 rad/s at t=2Then the angular (rotational) speed is constant (w=20 rad/s) for both t=3 and t=4.here's the graph: http://i.imgur.com/fOkTl.pngHow many revolutions does the object make during the first 4 s?
