force of friction on the cart is given as
here we also know the reaction force due to surface
so we can say reaction force is given as
now by force balance we will say
also we know that
now minimum force required to set this into motion
here we know that
So it will require 259 N minimum force to move it
The spring constant will be k= 5.5N/m for a 200g air track glider attached to a spring.
<h3>What is spring constant?</h3>The spring constant, k, is a measure of the stiffness of the spring. It is different for different springs and materials.
Calculation for What is the spring constant
First step is to calculate the time period
T = 12 second/10
T = 1.2 second
Now let calculate the spring constant using this formula
Where,
m=0.2kg
T=1.2second
k represent spring constant=?
Let plug in the formula
k=5.48 N/m
k=5.5 N/m ( Approximately)
Therefore the spring constant will be 5.5 N/m
