If a vector that is 1 cm long represents a velocity of 10 km/h, what velocity does a vectory 2 cm long drawn to the same scale represent?

10 km/h x 2 cm/1 cm=??

I am in 8th grade. I'm taking advanced classes.

To find the velocity represented by a vector 2 cm long, we need to determine the scale factor between the length of the vector and the velocity it represents.

Given that a vector 1 cm long represents a velocity of 10 km/h, we can set up the following ratio:

1 cm / 10 km/h = 2 cm / x

To solve for x (the velocity represented by a 2 cm long vector), we can use cross-multiplication:

1 cm * x = 10 km/h * 2 cm

Simplifying this equation, we get:

x = (10 km/h * 2 cm) / 1 cm
x = 20 km/h

Therefore, a vector 2 cm long drawn to the same scale represents a velocity of 20 km/h.

You have to be kidding.

If you are having difficulty with this, then Physics will be very anguishing for you. What you are asking is normally a seventh grade mapping skill.

Use proportions:
1cm/10= 2cm/x
