  The Singapore Flyer has a diameter of 150m.If the flyer is capable of rotating at a constant speed of of 10 minutes per revolution. Find the angular velocity and acceleration if you are inside one of the cars when its is the highest point of the circumference.

  Rotating at Constant speed means constant angular velocity

  1 revolution = 2*pi rad

  so 2*pi rad in 10 * 60 = 600s

  Hence, angular velocity = 0.0105 rad/s

   

  acceleration refers to centripetal acceleration = rω^2

  At highest point, total acceleration downwards = rω^2 + gravitational acc = 10.6

  looks like standard A level physics question to me...

  eagle u sure can add centripetal acceleration with gravitational acceleration? i got the velocity correct, but i think cannot add gravity..

  not exactly sure what the question wants also... :(

  Just tweak accordingly lor...

  no SP teacher gave me this question b4.

  Topic on Kinetic of particles-Force and acceleration

  don know how to study for this module..any guide?

  dunno... me not trained in Engineering Mechanics

  Anyway you could still post your questions... It still seems like the questions I did during A levels... I presume you are in your first year?

  Thanks.bascially i think it is another name for physic in some way..i am in second year..."acceleration refers to centripetal acceleration " btw wad is this formula?

  this one really is JC work.. rw^2.. or can convert to (mv^2)/r..
