Answer:
Full range of motion of a human arm.
Explanation:
Excavator arms have three articulations. Just like a shoulder, elbow, and wrist.
relation between linear velocity and angular velocity is given as

here
v = linear speed
R = radius
= angular speed
now plug in all data in the equation



so rotating speed is 60.9 rad/s
Answer: East Coast
Explanation:
The problem states we need to find whether the person is on the East Coast or West Coast.
Now, we know that the shadow is shortest when the Sun is at the highest point in the sky. So it means the noon time is 12:00 P.M. Now this is the local noon time which you have set in Kansas City. Now you flew to the Coast and it says 10:00 am which means you have traveled to a place where noon comes early. And noon comes early on Eastern Coast so you are on the East Coast.
Answer:

Explanation:
It is given that,
Mass of bundle of shingles, m = 10 kg
Upward acceleration of the shingles, 
The radius of the motor of the pulley, r = 0.17 m
Let T is the tension acting on the shingles when it is lifted up. It can be calculated as :



T = 113 N
Let
is the minimum torque that the motor must be able to provide. It is given by :



So, the minimum value of torque is 19.21 N-m. Hence, this is the required solution.
