A man walke towards the bus stop 100 meters away at a constant velocity. He reaches the bus stop in 200 seconds. Once at the bus

serg [7]

First:

d = 100 m
t = 200 sec

v = 100/200 = 0.5 m/s

Displacement is zero since he returned to his start point.

t2 = d/v2 = 100/2 = 50 sec

total time = 50 + 200 + 500 = 750 sec

Two ponies of equal mass are initially at diametrically opposite points on the rim of a large horizontal turntable that is turni

AleksandrR [38]

Answer:A

Explanation:

Given

Two ponies are at Extreme end of turntable with mass m

suppose turntable is moving with angular velocity $\omega$

Moment of inertia of Turntable and two ponies

$I=I_o+2mr_0^2$

let say at any time t they are at a distance of r from center such $r$

Moment of inertia at that instant

$I'=I_0+2mr'^2$

$I'$

conserving angular momentum as net Torque is zero

$I\omega =I'\omega '$

$\omega '=\frac{I}{I'}\times \omega$

$\omega '>\omega$

Thus we can say that angular velocity increases as they move towards each other.
