Answer:
Step-by-step explanation:
a=30
b= 17
c= 18
we actually already found angles B and C for the last problem I think we said 30 and 32 so we would be able to guess that angle A is about 118° but.. let's do the math... and see
angle A = arcCos[ b^2 + c^2 - a^2 / 2*b* c ]
A = arcCos[ 289 +324 - 900 / 2*17*18]
A = arcCos[ -287 / 612 ]
A = arcCos[ -0.468954 ]
A = 117.9664 °
ohh and we're off by 0.0336 phooy :P soo far off... :P
rounding to nearest 10th
A = 118.0 ° ( ohh right on the money :P) yay, I feel better. :P
The angular velocity is 16 radians per second
<u>Solution:</u>
The angular velocity of point is given by formula:
Where,
w is the angular velocity in radians
v is the linear velocity
r is the radius
Given that diameter of wheel is 10 feet
Thus radius is 5 feet
A point on the rim of a wheel moves with a velocity of 80 feet per second
Linear velocity = v = 80 feet per second
Therefore, angular velocity is given as:
Thus angular velocity is 16 radians per second
