An un-tethered block sits on a flatbed truck as it accelerates up an incline that makes an angle of 15° with respect to the horizontal. If the truck speeds up at a rate less than 2.50 m/s2, the block remains on the truck. If the truck speeds up at a rate equal to or greater than this value, however, the block slides off the truck. What is the coefficient of static friction between the truck and the block?
Ok so i understand that tan(15) gives me the coef if the trunk is motionless i think? (.267)
And when it has motion i need to account for Normal Force which is Fn= M* G
But i cannot figure out how i get the mass. Assuming something to do with the 2.50 accel but i am stuck any tips would be great.
Fs = n tan angle also found that but still can't figure out how to get Fn
