An object of inertia 0.5kg is hung from a spring, and causes it to extend 5cm. In an elevator accelerating downward at 2 m/s^2 ,
Sidana [21]

Answer:3.98cm

Explanation:

given data

mass of object\left ( m\right )=0.5kg

intial extension=5 cm

elevator acceleration=2 m/s^2

From FBD of intial position

Kx=mg

K=\frac{0.5\times 9.81}{0.05}

k=98.1 N/m

From FBD of second situation

mg-kx_0=ma

kx_0=m(g-a)

x_0=\frac{0.5(9.81-2)}{98.1}

x_0=3.98cm

What if The rotational speed of Earth increased ?
dsp73

Answer:

This would happen.

Explanation:

If the earth’s rotation speed increases then the weight of the body decreases. This is because you see a moving body on the rotating earth’s surface itself is in the reference frame. So when the earth rotates, the centripetal force acts towards the centre of rotation.
