Answer:
91 rad/s
Step-by-step explanation:
The relationship between angular velocity (ω) and constant angular acceleration (ω') is ...
ω(t) = ω0 + t·ω'
ω(0.25) = 95 = ω0 + 0.25(16)
95 -4 = ω0 = 91 . . . rad/s
The initial angular speed was 91 radians per second.
40 = n x 11; 23.4 % this is wat i got
Answer:
(assuming you are knowledge about Pythagoras theorem)
44.205
Step-by-step explanation:
draw the altitude line to the upper right corner and the lower left corner and you have 2 identical right triangles and a rectangle. If you solve the third side of the right triangles you get 1.685 (sqrt[7.2^2 - 7^2]).
now add up the areas of both triangles and the rectangle in the center whose base is 4.63 (subtract the 3rd side from 8)
you have
1.685(7) + 7(4.63)
This it the test please do as fast as posible and show work. thank you and sorry
