What is the coefficient of kinetic friction between the block and the surface? Provide your answer using two significant figures.
Response:
0.39
To elaborate:
The provided data includes
m1=1.7 Kg
m2=0.011 Kg
v2=670 m/s
d=2.4 m
The relationship m2v2=(m1+m2)v applies here hence
also 
Friction's deceleration can be calculated using

thus 


The equation for simple harmonic motion (SHM) is as follows.
Answer:
The duration, t = 3.53 seconds
Explanation:
The following information is provided:
The equation to calculate the time t is expressed as:
...... (1)
Where
s denotes the distance in feet
We are to determine the duration taken by the stone to fall a distance of 200 feet, where s = 200 feet
Substituting the value of s into equation (1) yields:

t = 3.53 seconds
Thus, the time taken by the object is 3.53 seconds, which provides the required answer.
