Question: Learning Goal: To practice Problem-Solving Strategy 5.2 Newton's Second Law: Dynamics of Particles.
You want to move a heavy box with mass 30.0 kg across a carpeted floor. You pull hard on one of the edges of the box at an angle 30 degrees above the horizontal with a force of magnitude 240N , causing the box to move horizontally. The force of friction between the moving box and the floor has magnitude 41.5 N . What is the box's acceleration just after it begins to move?
Find both the x and y components of the acceleration of the box.
A normal walking speed is around 2.0 m/s . How much time t does it take the box to reach this speed if it has the acceleration 5.54 m/s^2 that you calculated above?
