Calculating the Force Pressing the Lawn Mover to the Ground


Given:
  • Force applied: 50N
  • Angle with the ground: 30 degrees


Step 1: Finding the Vertical Component of the Force

  • Vertical component = Force * sin(angle)
  • Vertical component = 50N * sin(30°) = 50N * 0.5 = 25N


Step 2: Determining the Force Pressing the Lawn Mower to the Ground

  • Since the lawn mower is not moving vertically, the force pressing it to the ground is equal to the vertical component of the force applied.
  • Therefore, the force pressing the lawn mower to the ground is 25N.


Explanation of Why the Lawn Mower Moves Forward and Not Downward

When the force is applied at an angle, it can be resolved into two components: vertical and horizontal. In this case, the vertical component (25N) is responsible for pressing the lawn mower to the ground, while the horizontal component (50N * cos(30°) = 43.3N) is responsible for propelling the lawn mower forward. The ground exerts an equal and opposite reaction force on the lawn mower, which allows it to move forward without sinking into the ground.
