θ = tan^(-1)(-30.3 km / 37.5 km) = -38.3°
So, the magnitude of the resultant displacement is 48.2 km, and its direction is 38.3° south of west.
The force acting on the block is:
:
The acceleration of the block is 4.90 m/s^2. θ = tan^(-1)(-30
:
"Principles of Physics: A Calculus-Based Text" by David Halliday, Robert Resnick, and Jearl Walker is a widely used textbook in introductory physics courses. The 5th edition of this book provides a comprehensive introduction to physics, using calculus as a mathematical tool. Here are some key principles and solutions from the text: θ = tan^(-1)(-30
Let's break down the displacement into its north and west components:
