1. When calculating a car's acceleration, is it ok to substitute Torque into a= F/ma= F/m
T= FrF= T/rwhere
a= acceleration,
F= force,
m= mass,
T= Torque,
r= radius,a= T/rm ?
So the force vector on the block's perpendicular to the red dot?
If I'm correct, if a force is applied on an object's centre of gravity( generally center of mass), it will displace; Elsewhere, it'll turn.
Are you using the right angle triangle Sin Y°= Opposite/ Hypothenus formula?
But is the...
Another thinner block of wood screwed to the machine arm, as shown.
It has to be attached to something at its end, so yes.
I think there's no difference to the perpendicular force vector to the arm, what do you mean, maybe a picture can explain better?
No, the question is simply "Did the block of wood successfully act as a lever directing the force perpendicular to the arm of the machine, as the red arrow indicates?".
I'd like to ask the question as above, I think it successfully acted as a lever and redirected the force vector perpendicular to the arm of the machine, but it does've > friction, reducing the force acting on the 10kg Weight, could anyone that knows pls help check for me?*Edit, ... I think it...
A) Questions, Equations & Attempts on answering
1) If I'm correct, for linear cases, Work= Fs,
F= Constant Force
s= Displacement
where Work can= negative if displacement ends up in the opposite direction, am I right?
2) Rotational Work= Fs

Well I've drawn my amplitude all above x-axis as the E_{p} starts from 0-origin,then increases to max then back to zero again,forming a sinusoidal wave type pattern.The graph requested didn't put a requirement to be exact in amplitude.How different u mean?

Hi,the question is draw a graph of E_{p} against t/s of the oscillating motion above,I've done it and have no exact answer in my hand,hoping some ppl to double check my answer that's all.My answer is here below

Two markers M1 & M2're set up a vertical distance h apart.
When a steel ball is released from rest from a pt a distance x above M1,it's found that the ball takes time t1 to reach M1 and time t2 to reach M2.
Which expression gives the acceleration of the ball...
I've redone the stuff u said,also added 1 more question needing to be answered,should be easy for pros out there.Pls do me a favour which is answering it?!
