Should be option 1. i cant really gv an explanation tho sry :/
Answer:
Step-by-step explanation:
Given
The attached triangle
Solving (a) BA
Considering the tangent of angle C, we have:
This gives:
Make BA the subject
--- approximated
Solving (a) BC
Using Pythagoras theorem
Square root of both sides
Answer:
d = 101
Step-by-step explanation:
t = 11
11 x 11 = 121
-20 + 121 = 101
check: 101- 121 = -20 (correct)
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
