Nb

a). acceleration of the block

b). coefficent of kinetic friction between the block and the incline

c). frictonal force acting on the block

d? the speed of the block after it has slid 2.00m

u = 0 m/s

v = v

a = a

s = 2.00 m

t = 1.50 s

mass=3.00 Kg

a) Use the formula: s = ut + 0.5 a t^2

b) Since the block is sliding, F = [mu] R

Therefore [mu]=Tan30

c) Since F = [mu] R

F = Tan30 * 3.00*9.81*Cos30

d) Using the u, v, a, s, t that I wrote down before, substitute values into this equation:

v = u + a t

Hint: For this type of question, I highly recommend drawing a diagram with all the information on at the very start of the question before you do anything else, it will help you to visualize the question and also contains key information that you can remind yourself of at a quick glance.
