A 200 g air-track glider is attached to a spring. The glider is pushed in 9.8 cm against the spring, then released. A student with a stopwatch finds that 12 oscillations take 15.0 s. Part A What is the spring constant

k =  5.05 N/m

Explanation:

In order to calculate the spring mass of the system, you use the following formula:

    (1)

T: period of oscillation of the system

m: mass of the air-track glider = 200g = 0.200 kg

k: spring constant = ?

You first calculate the period of oscillation:

Next, you solve the equation (1) for k, and then you replace the values of the other parmateres:

The spring constant of the spring is 5.05 N/m

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
