Wheel with radius 3 m rolls at 18 rad/s. how fast is a point on the rim of the wheel rising when the point isπ/3 radians above the horizontal and rising? round to one decimal.

The point is rising at a speed of 27 m/s.

Step-by-step explanation:

The rim is represented in the figure that is attached

The tangential speed of the point on the rim is given by

Applying values we get

Resolving the speed along the x and y axis as shown in the figure we get

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
