Homework Statement


The minute hand on a watch is 2.0cm in length. What is the displacement vector of the tip of the minute hand:
a. from 8:00 to 8:20
b. From 8:00 to 9:00


Homework Equations




The Attempt at a Solution


I keep getting that the displacement is 1.8,2.8, but the program we have to put it in for class it keeps frickin saying "Almost... blah blah blah some crap about checkin sig figs.

How are you arriving at these results?

A displacement vector consists of a magnitude and direction.

In other words, after 20 minutes, how far did the tip of the minute hand move and in what direction?
 

What is vector displacement?

Vector displacement is a term used in physics to describe the change in position of an object in a particular direction. It is represented by a vector, which includes both magnitude and direction.

How is vector displacement related to the tip of minute hand?

In this context, vector displacement refers to the change in position of the tip of the minute hand on a clock. It is used to describe the movement of the hand as it goes from the 8:00 position to the 8:20 position and then to the 9:00 position.

Why is the minute hand used to demonstrate vector displacement?

The minute hand on a clock is a perfect example of uniform circular motion, which involves both displacement and velocity. It is used to demonstrate vector displacement because it moves in a circular path, making it easier to visualize and understand.

Can vector displacement be negative?

Yes, vector displacement can be negative. This means that the object is moving in the opposite direction of the positive vector. In the context of the minute hand, a negative vector displacement would indicate that the hand is moving counterclockwise instead of clockwise.

How is vector displacement calculated?

Vector displacement is calculated by subtracting the initial position vector from the final position vector. This gives the displacement vector, which includes both magnitude and direction. In the case of the minute hand, the displacement vector would be the difference between the 8:00 and 9:00 positions.
