A mass on a spring with k=88.7 N/m oscillates 15 times in 9.24s. what is the objects mass? unit=kg?
sweet [91]

The mass on the spring is 0.86 kg

Explanation:

The period of a mass-spring system is given by the equation

T=2\pi \sqrt{\frac{m}{k}}

where

m is the mass

k is the spring constant

In this problem, we have:

k = 88.7 N/m is the spring constant

The system makes 15 oscillations in 9.24 s: therefore, the period of the system is

T=\frac{9.24}{15}=0.62 s

Now we can re-arrange the first equation  to solve for the mass:

m=k(\frac{T}{2\pi})^2=(88.7)(\frac{0.62}{2\pi})^2=0.86 kg

Can there be displacement of an object in the absence of any force acting on it? Think, Discuss it with your friends and teacher
Fudgin [204]

Answer:

An object can have a displacement in the absence of any external force acting on it

Explanation:

When a object moves with a constant velocity (v), then it gets displaced in the direction of motion but the net external force experienced by the object is zero.

F  external  =ma

If object moves with constant velocity, acceleration is zero.

Since, a=0  ⟹F  external  =0

Using  s=ut+  1/2 at  ^2

 ⟹    Displacement    s=ut    (∵a=0)

Hence, an object can have a displacement in the absence of any external force acting on it

Hope this helped you:)
