How Do You Solve for V2 in a Vector Acceleration Problem?

Click For Summary
SUMMARY

The discussion focuses on solving for V2 in a vector acceleration problem using the equation V2 = delta velocity + V1. The user describes V1 as a vector of 3 cm at an 80-degree angle and a change in velocity of 5.1 cm directed downwards at 90 degrees. The scale provided is 1 cm = 1 km. The user successfully drew the vectors but seeks further assistance on the next steps to calculate V2.

PREREQUISITES
  • Understanding of vector addition and representation
  • Familiarity with trigonometric functions for angle calculations
  • Knowledge of units and conversions (cm to km)
  • Basic physics concepts related to velocity and acceleration
NEXT STEPS

I'm having trouble with finding V2 using the vector diagram I'm given.
I know the equtaion I have to use is V2 = delta velocity + V1

Here's a description of the diagram.
I have the V1 vector going up 3cm at an 80 degree angle. The change in velocity is 5.1cm down at 90 degrees. And the scale I'm given is 1cm = 1km.

I drew the two vectors togther on one diagram, but I don't know what to do next. Can someone help me please?
