Work Problem, opposing forces (no friction)

AI Thread Summary
The discussion focuses on calculating the work done on a block subjected to two opposing forces, T1 and T2, on a frictionless surface. The work done by T1 is calculated as 352 J, while the work done by T2 is -209 J, indicating it acts in the opposite direction. The work done by gravity and the normal force is zero since they act vertically while the displacement is horizontal. The net work done on the block is the sum of the work done by T1 and T2, which totals 62 J. The participant confirms their calculations and resolves their initial uncertainty about finding the net work.

Homework Statement


In the figure below,

http://www.webassign.net/userimages/jshemwell@lincolnpark.il/Net%20Force/Two_opposing_horizontal.gif

T1 = 32 N, and T2 = 19 N. The surface has no friction. The block travels a displacement of 11 m to the right as a result of these forces.
a. What is the work done on the block by T1?

b. What is the work done on the block by T2?

c. What is the work done on the block by gravity?

d. What is the work done on the block by the normal force?

e. What is the net work done on the block by all forces?

Homework Equations


The Attempt at a Solution


I got (32N)(11m)(Cos0)=325 J for a.
I got (19N)(11m)(Cos180)=-290 J for b.
I got 0 for c. and d.
I am not sure how to find e. and did I do the rest of the problems correctly?

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

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 hanged mass'

Thread 'A cylinder connected to a hanged 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...
