A truck lifts a heavy weight using a pulley system. At the instant shown the velocity and acceleration (with positive defined to the right) are: vt=9.6m/s and at=1.7m/s² respectively. The angle of the cord to the horizontal is β=30 degrees. What is the acceleration of A, with respect to the coordinate system shown for A?

what do you want ?!
anonymous

The acceleration of mass A, at the moment where the truck is moving in the rightward direction at a velocity 9.6m/s and an acceleration of 1.7m/s/s. Mass of pulleys are assumed negligible, and frictionless. If no one understands here, I'll leave this question for next week and ask my lecturer :)

A=?in problem ?
anonymous
  • anonymous
A is just a block. I'm assuming mass doesnt matter, as its not mentioned in the question
anonymous
  • anonymous
But its Important !

Do you want V?
anonymous
  • anonymous
Just acceleration of the block A, as a result of the truck

v=1/4m/k under Radical

I'm pretty sure its to do with solving via coordinate systems (polar/cartesian/t-n) - some stuff we just worked on in class. I'll probably leave the question for later and ask the lecturer or a friend. thanks anyway
