AI Thread Summary
When a man pushes a 20 kg lawnmower at a constant speed with a force of 100 N at a 35° angle, the horizontal retarding force acting on the mower can be calculated using the applied force's horizontal component. The vertical component of the applied force affects the normal reaction force from the ground, which must also be considered. The weight of the mower is calculated using the formula w = mg, and the forces acting on the mower include the applied force, gravitational force, and frictional forces. The discussion emphasizes resolving the applied force into its components to analyze the system accurately. Understanding these forces is crucial for determining the mower's behavior under the given conditions.

5 A man pushes a lawnmower of mass 20 kg at a
constant speed with a force of 100 N directed along
the handle, which is at 35° to the horizontal.
a What is the horizontal retarding force on the
mower?
b What is the perpendicular reaction of the ground on
the mower?

What are your thoughts on this?
 
i don't know
but i tried w=mg
then i applied wsin35
but it was incoorect
 
Resolve the force the man applies along the axes. What are the other forces acting on the mower?
 

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 'A cylinder connected to a hanging mass'

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...
