1. At the end of a factory production line, boxes start from rest and slide down a 34° ramp 5.4 m long. If the slide is to take no more than 3.2 s, what is the maximum allowed frictional coefficient?

Hi Robertoalva,

Could you show where you are stuck in the problem please?
 
I don't know how to use the equation for the frictional coefficient! I suppose that I have to use another equation that uses time, but I'm not so sure!
 
Well, frictional coefficient is the ratio of the magnitudes of the normal force and maximum frictional force possible.

Knowing that, what would be the acceleration of the block?
