Problem
A warehouse worker pushes a crate with a constant horizontal force of 50N. The crate is moved from point A to point B on the smooth floor by two different routes as described below.
Route 1: A straight line path of length 10m.
Route 2: A curved path of length 12m that starts and ends at the same points A and B.
Answer the following.
(i) Calculate the work done by the worker on the crate along Route 1.
(ii) Calculate the work done by the worker on the crate along Route 2.
(iii) Which route requires more work on the crate? What inference do you draw about the physical quantity on which work depends?
