Homework Statement
Hi all, I have solved these problems just wanted to see if it's all ok
problem 1:
a trolley starts at the lowest point of a diagonal plane with a 20m/s speed. Its acceleration is 4m/s^2 going downhill, the trolley goes up then slows until it reaches 0 speed and then goes...
Thank u for your patience!
I have this:
1.
m1(A)g = m2(B)g = 20Kg
X = 1m
mag • sinα – T = m1a
T = m2a
mag • sinα -T + T = m1a + m2b
200 • 0.60 = a(m1 + m2)
a = 120/40 = 3m/s
X = V0T + at^2 /2
1 = 0 + 3t^2/2
2 = 3t^2
t = 0.816s
2.
T = m2a
T = 20 • 3 = 60N
there are two more...
Homework Statement
Log A weighs 20Kg is laid on a diagonal smooth plane with a diagonal angle of 27 37 degree, log A is tied by a rope to the head of the plane and there through a wheel with no friction the rope descend vertically to the bottom of the plane and through another friction-less...
tyvm!
yes, I wondered about that but the other way around, thought it will travel less, it seemed to make sense intuitively - that heavier objects will travel less distance, obviously it doesn't - why? is that due to inertia as you mentioned?
ty!, noted!
Homework Statement
Hi, would like to get a feedback on my answer to this question, did I do it right?
In part 2 of the question is there another way to calculate distance with friction?
the question is:
a disc is moving on icy surface has an initial speed of 12m/s 42m until it stops
1. what...
haha you make my efforts look so complicated when there's a clean simple answer
and I calculated when calc is on degree, that's how my teacher wants it, I thought I can't use Pythagoras I can't remeber why now, very new to all of this, is what I did legit at all? cause if its is (-) then result...
