A 3.00 kg block starts from rest at the top of a 36.0'> incline and slides 2.00 m down the incline in 1.60 s.
(a) Find the acceleration of the block.
m/s2

(b) Find the coefficient of kinetic friction between the block and the incline.


(c) Find the frictional force acting on the block.
N

(d) Find the speed of the block after it has slid 2.00 m.
m/s

  • physics - ,

    acceleration=changevelocity/time= 2avgvel/time

    average velocity= distance/time

    B) you know final velocity(2*avg velocity)

    Hmmm. I don't see how it can be done without slope.
