Explanation:
<u>Circular Motion</u>
One point located at a distance r from the center of rotation travels a distance L given by the arc length :
Where 
is the angle formed during the rotation.
The wheel described in the question has a radius r=4.1 m and a point on the wheel rotates some angles given in each part:
a) 
Calculating L
b) 
c) 
<u>D. 475 </u>
Explanation:
The numbers do not increase much more then this, so it must be the max
Answer:
They do not differ because 6.2 is the same as 6.20
Explanation:
Answer:
0.2m/s2
Explanation:
acceleration= change in velocity ( in this case speed)/ change in time.
4.5-3.5=1m/s
change in time=5-0 =5
1m/s divided by 5 seconds acceleration as the result
