In this lesson, we will learn how to calculate the resultant vector of multiple linear accelerations that are at angles to each other.

Q1:

A spaceship is traveling at a constant velocity v i = 2 5 0 / m s when its rockets fire, giving it an acceleration a i j = ( 3 . 0 0 + 4 . 0 0 ) / m s 2 . What is the spaceshipβs velocity 5.00 s after the rockets fire?

Q2:

The position of a particle is given by r i j k ( π‘ ) = ( 4 . 0 π‘ β 3 . 0 + 2 . 0 π‘ ) 2 3 m .

What is the velocity of the particle at 0.0 s?

What is the velocity of the particle at 1.0 s?

What is the average velocity of the particle between 0.0 s and 1.0 s?

Q3:

A particle has the position function r i j k ( π‘ ) = ( ( 1 0 π‘ β π‘ ) + 5 π‘ + 5 π‘ ) 2 m. What is the acceleration vector of the particle?
