What is the coefficient of kinetic friction between the block and the surface? Express your answer using two significant figures.
Answer:
0.39
Step-by-step explanation:
Given information
m1=1.7 Kg
m2=0.011 Kg
v2=670 m/s
d=2.4 m
m2v2=(m1+m2)v hence
and also

The deceleration due to friction is given by

therefore

Therefore,
