Projectile Motion (2) Homework - Labeling Points, Drawing Vectors

[kevin948]

Homework Statement

(I attached diagram)

The motion diagram shown on the attachment represents the position of a projectile in flight at 1 seconds intervals in tie. The projectile starts at the origin of the coordinate system.

a) Label the points 0 to 6

b) Draw the average velocity vectors for each interval on the diagram, labeling them

- - -
V₁,V₁₂,...,V56 (- mean vector)
- - -
c) Take the acceleration vector at point 1 to be a₁= V₁₂-V₁/△t
and draw this vector on the diagram with its tail at point 1. Repeat this procedure for points 2 through 5.

d ) Find the numercial values for each of the velocity vectors in pard (b) and each of the acceleration vectors in part (c), leaving them with the unspecified units for distance.

e) How mant meters does each distance unit represent?

The Attempt at a Solution

I have no idea about this problems...please help me

I'll assume you can do (a), but just to be sure I'll mention that the "0" goes in the lower left and the "6" in the lower right.

(b) What is the definition of average velocity? That will be useful here.
