I got 29.2799 for the final answer. it is wrong

yeah I understand the no net force thing...and resolving vertical and horizontal forces...using sin and cos. yes...

don't really understand that... could you tell me what formulas to use? thanks

Homework Statement A m = 2.7 kg wood box slides down a vertical wood wall while you push on it at a θ = 35° angle. What magnitude of force should you apply to cause the box to slide down at a constant speed? Homework Equations The Attempt at a Solution I got 64.5766 N for the...

it says Ay is wrong. For diagram B...how would I do it?

Ax : 3sin(20)=1.02606 F = -1.02606-1+5 = 2.97394 = 2.97394/2.6 = 1.14382 Ay : 3cos(20)= 2.81908 F = -2.81908 + 2.82 = 0.000922 = 0.000922/2.6 = 0.000355

For x comp. of 3N = 1.02606 y= 2.81908 My guess for F net is 2.97394... ax = F/M 1.14382?ay = .000354 wrong

Homework Statement In each of the two free-body diagrams, the forces are acting on a 2.6 kg object. For each diagram, find the values of ax and ay, the x- and y-components of the acceleration, with F1 = 5 N and F2 = 3 N. Picture is attached. (a) Diagram A ax =____ m/s2 ay =____ m/s2 (b)...

Homework Statement A horizontal rope is tied to a 23 kg box on frictionless ice. What is the tension in the rope under each of the following conditions a) the box is at rest. b) the box moves at a steady 5 m/s c) the box has Vx= 5 m/s and Ax = 5 m/s^2 Homework Equations The...

Homework Statement Two rubber bands pulling on an object cause it to accelerate at 1.6 m/s2 (a) What will be the object's acceleration if it is pulled by six rubber bands? Answer: 4.8 m/s/s (correct) (b) What will be the acceleration of seven of these objects glued together if they are...

Homework Statement Let A= (3.5 m, vertically downward) and B = (4.1 m, 120° clockwise from ). Find the x and y components of and in each of the two coordinate systems shown in Figure Ex3.21. (attached) Homework Equations The Attempt at a Solution I already have 0 for the x...

which equation do I use? is there a way you could show me the first step?

acceleration is zero

I think his speed is staying the same... doesn't his direction stay the same as well

i have no clue...i am confused
