Question

Plot the equation v = 6 m/s from t = 0 to t = 10 sec. (Remember v is on the vertical axis and t is on the horizontal axis.) What is the v-intercept? (Include units) ______________. This horizontal line tells us that the velocity at any time is 6 m/s.

Answer 1

The v-intercept is 6 m/s

Explanation:

In the velocity time graph

The vertical axis represents the velocity of the object v in meters per second, and the horizontal axis represents the time in seconds

∵ The equation is v = 6 m/s

- It is a constant equation because value of v does not depend on t

∵ t = 0

∴ v = 6 m/s

∵ t = 2 seconds

∴ v = 6 m/s

∵ t = 10

∴ v = 6

- That means v is equal to 6 at any value of t

∴ v is represented graphically by a horizontal line

∵ v-intercept means value v at t = 0

∵ At t = 0 v = 6

∴ v-intercept is at (0 sec , 6 m/s)

∴ The v-intercept is 6 m/s
