A 53 kg block sliding horizontally across the floor has a coefficient of static friction of us = 0.42 and a coefficient of kinetic friction of HK = 0.26. If it was sliding at an initial speed of 4.4 m/s, how far will it travel before stopping?

Question
PleAse help me to check if the answer for the question on the first image is correct. My work is on the second image
and if I have included the proper units. If not please correct it
Transcribed Image Text:A 53 kg block sliding horizontally across the floor has a coefficient of static friction
= 0.42 and a coefficient of kinetic friction of μ = 0.26. If it was sliding at an
initial speed of 4.4 m/s, how far will it travel before stopping?

Transcribed Image Text:Given
m = 53 kg
- P²₁ = 0.42
-P₁ = 0,26
- u = 4.4 m/s

- g = 9,8 m/s ²
When an
object slides, it is the kinetic friction which comes inks
the picture. In this problem the object is sliding hence
coefficient of kinetic every friction (PK) will be used
acceleration (a) of the object will be
a=Pkg
19 = 0.26 x 9.8 m/s
19 = 2.548 m/s ²
