a 100kg box of dimension 50cm*50cm*50cm is in the back of a tray truck. The coefficients of friction between the box and the bed of the truck are Us=0.4 and Uk=0.2.
What is the maximum acceleration the truck can have without the box slipping?

is the answer 392N?

anonymous · Answer

the answer is not 392N...just realised acceleration is needed

anonymous · Answer

ok so is it 392m/s^2?
seems pretty fast...

anonymous · Answer

ohhh
actually is it
f=ma
392=100a
a=3.92m/s^2
