A 25 kg rocket was launched, heading north, with a force of 500 N from each of its two engines. It was pushed westward by a 200 N wind and was also slowed by 400 N of air resistance. What was the resulting direction, net force, and acceleration of the rocket?

Steps to Solve a Vector Problem:
Set up your scale (ex. 10 cm = 10 N). Draw vectors, tip to tail. Use color to draw “net force” vector. Measure to figure out net force.

Practice Problems: 1. The bird flew north with a force of 6 N, but was slowed by 2 N of air resistance (south). Meanwhile, the wind blew 1 N to the West. What was the net force acting on the bird? 2. A 25 kg rocket was launched, heading north, with a force of 500 N from each of its two engines. It was pushed westward by a 200 N wind and was also slowed by 400 N of air resistance (south). What was the resulting direction, net force, and acceleration of the rocket?
