Solving Work Done by Pushing a Lawnmower

AI Thread Summary
To solve the problem of work done by pushing a lawnmower, the force applied is 200N with a vertical component of 80N. The horizontal distance moved is 6.0m, and the work done can be calculated using the formula Work = force x distance. To find the effective horizontal force, the angle of the applied force needs to be determined, which involves using trigonometric functions. The discussion emphasizes the importance of sketching the scenario and applying Pythagorean principles to find the angle correctly. Understanding these concepts is crucial for accurately calculating the work done.

Homework Statement


A man pushes a lawnmower with a force of 200N. If the vertical component of this force is 80N how much work is done in pushing the lawnmower 6.0m horizontally?

Homework Equations


Work=force x distance

The Attempt at a Solution


Firstly I have to find the angle to the ground at which the 200N force is directed.
However i am not sure on how to do that.

Would the angle be 68 because inverse tan(200/80)
 
68 radians ? No, degrees I hope.
Never mind: once you have the angle, what are you going to use it for ?
And: Sketch ?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
