An object with a mass of #4 kg# is acted on by two forces. The first is #F_1= < -2 N , -6 N># and the second is #F_2 = < 5 N, 2 N>#. What is the object's rate and direction of acceleration?
The rate of acceleration is
Directed along the vector
Let's add two vectors that represented these two forces:
Now, applying the Second Newton's Law, acceleration is a vector with the following components:
The rate of acceleration is the length of this vector:
