Dan and Sue cycle at the same speed. The tires on Dan’s bike are larger in diameter than those on Sue’s bike. Which wheels, if either, have the greater rotational speed?
![Check Mark](/static/check-mark.png)
The wheel which have greater rotational speed if D and S cycle at the same speed.
Answer to Problem 27A
Explanation of Solution
Introduction:
A linear speed
Where,
Since the diameter of the tires of D’s bike is greater than that of the S’s bike, thus
Now, both the D and S cycle at same speed, thus the rotational speed of the tires of the D’s and S’s cycles will be,
Conclusion:
Hence, the S’s cycle will have the greater rotational speed.

- No chatgpt plsarrow_forwardIn a naval battle, a battleship is attempting to fire on a destroyer. The battleship is a distance d1 = 2,150 m to the east of the peak of a mountain on an island, as shown in the figure below. The destroyer is attempting to evade cannon shells fired from the battleship by hiding on the west side of the island. The initial speed of the shells that the battleship fires is vi = 245 m/s. The peak of the mountain is h = 1,840 m above sea level, and the western shore of the island is a horizontal distance d2 = 250 m from the peak. What are the distances (in m), as measured from the western shore of the island, at which the destroyer will be safe from fire from the battleship? (Note the figure is not to scale. You may assume that the height and width of the destroyer are small compared to d1 and h.)arrow_forwardNo chatgpt plsarrow_forward
