Please can you tell me if my diagram is correct and how i did it is correct
Is this correct that I can use 31 for my angle because it an opposite angle to the angle given in the picture
Please can you tell me if my diagram is correct and how i did it is...
Please help me check my answers to the following physics
problems. If they are incorrect, please explain the concept to me
so I may correct my mistakes.
1. A 60 kg skate-boarder rolls down an inclined sidewalk
at a 370 angle to the horizontal. A constant frictional force of 55
N acts on the skate-boarder in opposition to the motion. What is
the skate-boarder's acceleration?
[I got a=4.98 m/s2]
I'm stuck on number 2. I got
N=3.535 and a =...
Please help me with both parts
b and c. I am confused
Constants A 9.00 m uniform beam is hinged to a vertical wall and held horizontally by a 5.00 m cable attached to the wall 4.00 m above the hinge, as shown in the figure below (Figure 1). The metal of this cable has a test strength of 1.10 kN , which means that it will break if the tension in it exceeds that amount. Part A What is...
I know that D is the correct answer. Can someone please work
it out?
3. A uniform beam of mass M is attached to a wall by a pivot at one end and is held up at angle θ with the horizontal by a horizontal cable attached to the other end of the beam and the wall, as shown. If the beam is held at rest, the tension in the cable can be expressed as (A) ⅓MgCOTO f y Mg...
please explain why my lecturer solved it the way he
did. Why is thetta in his figure SW (to the right of the negative y
axis)? I put thetta on the WN (above the negative x axis) because I
know thats equivalent to the given one. Second, why does he include
the ma(dice) as a force? isnt this supposed to be what the sum of
our forces are equal too? why did he include it in the sum of
forces....
please tell me the answer and tell me why you chose it please help
me!! i would appreciate it

Can you please solve this question using clear detailed steps
and indicating the part number next to each and every answer
please? Thank you!
PS: WILL GIVE A THUMBS UP FOR THE CLEAREST CORRECT ANSWER :)
(1 point) A flexible cable suspended between two vertical supports is hanging under its own weight. The weight of a horizontal roadbed is distributed evenly along the x-axis with the density ρ = 2.9 lb/ft. The coordinate system is chosen so that the y-axis...
can someone tell me what i did wrong ?
A high-speed lifting mechanism supports a(n) 700-kg object with a steel cable that is 36.0 m long and 4.00 cm? in cross-sectional area. (a) Determine the elongation of the cable. (Enter your answer to at least two decimal places.) 3.9 х Your response differs from the correct answer by more than 10%. Double check your calculations, mm (b) By what additional amount does the cable increase in length if the object...
Can you please help me solve this with its part a b c and d?
(0%) Problem 13: A block of mass m = 3.4 kg is on an inclined plane with a coefficient of friction My = 0.31, at an initial height h=0.63 m above the ground. The plane is inclined at an angle 0 = 47°. The block is then compressed against a spring a distance Ax=0.11 m from its equilibrium point (the spring has a spring constant...
I got confused can you please explain to me how did he answer
this question, please I need to know in each step how did he do
it

Can someone tell me where I'm going wrong? I have these two
problems: The professor uploaded a video explaining how to solve
them (generally, he didn't use numbers. He said the steps are the
same for both problems except for the last step since the first
problem is asking for magnitude and the second is asking for an
angle. I followed his steps but I keep getting the wrong answer.)
Also for the 2nd question I'm not sure if I'm...
