I do not see that phrase in post #27. What did I write? Do you understand the differences?Jeff97 said:
Forces and vectors: pulling a baby buggy on soft ground
Click For Summary
SUMMARY
The discussion focuses on calculating the forces acting on a baby buggy being pulled on soft ground. The buggy has a mass of 25 kg and is pulled with a force of 100 N at an angle of 40 degrees to the horizontal. Participants clarify the need to calculate both the vertical and horizontal components of the pulling force, using trigonometric functions such as sine and cosine. The total force exerted by the buggy on the ground is determined by considering the weight of the buggy, calculated as 245 N (using F=mg), and the pulling force, leading to a comprehensive understanding of force balance in this scenario.
