Sally is working on her physics homework and is trying to figure out the following problem: "A student pushes a lawnmower with a constant force of 80 N at an angle 40 above horizontal. How much work does the student do after walking 10 m?" Sally reasoning is as follows: "If the student is constantly pushing with a force of 80 N for 10 m then they must be doing 800 J of work. Since they're pushing at an angle, it's just going to take them longer to travel the 10 m". Is Sally correct in her reasoning? Explain briefly using legible point form.
