Sound waves are longitudal waves meaning they go back and forth
Answer:
1.52905 seconds
4.58715 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
= Coefficient of friction = 0.4
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration = 
Equation of motion

It will take 1.52905 seconds for the block to slow down

The block will travel 4.58715 m before it stops
