(a) You pull a box with a constant force across a frictionless table using an attached rope held horizontally. If you now pull the rope with the same force at an angle to the horizontal (with the box remaining flat on the table), does the acceleration of the box increase, decrease, or remain the same? Explain, (b) What if there is friction?
We have to analyze the variation in acceleration when a force is applied is at an angle in absence and presence of friction.
Step 1 of 3
Newton’s second law: The force F acts on mass m produces an acceleration a in the object. Mathematically,
