The dimension of K is M/ T^2
according to the question T=2π square root ofm/k here 2 pi is constant so
T= root of m /k and root of k = root of m/ T now by squaring on both the sides we get the answer k= M/ T^2
complete question :
A spring is hanging down from the ceiling, and an object of mass m is attached to the free end. The object is pulled down, thereby stretching the spring, and then released. The object oscillates up and down, and the time T required for one complete up-and-down oscillation is given by the equation T=√2πm/k, where k is known as the spring constant. What must be the dimension of k for this equation to be dimensionally correct?

Complete Question
A rolling ball moves from
to
during the time from
to ![t_2 = 6.0s](https://tex.z-dn.net/?f=t_2%20%3D%206.0s)
What is its average velocity over this time interval?
Answer:
The velocity is ![v = 3.903 \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%20%203.903%20%5C%20m%2Fs)
Explanation:
From the question we are told that
The first position of the ball is
The second position of the ball is ![x_2 = - 4.1 \ cm](https://tex.z-dn.net/?f=x_2%20%3D%20-%204.1%20%5C%20cm)
Generally the average velocity is mathematically represented as
![v = \frac{ x_1 - x_2}{t_2 - t_1}](https://tex.z-dn.net/?f=v%20%20%3D%20%20%5Cfrac%7B%20x_1%20-%20x_2%7D%7Bt_2%20-%20t_1%7D)
=> ![v = \frac{ 8 - -4.1 }{ 6 - 2.9 }](https://tex.z-dn.net/?f=v%20%20%3D%20%20%5Cfrac%7B%208%20-%20-4.1%20%7D%7B%206%20-%202.9%20%7D)
=> ![v = 3.903 \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%20%203.903%20%5C%20m%2Fs)
