Physics

Velocity will be equal to 8.88 m/sec

Explanation:

We have given mass m = 500 kg

Length of cable l = 30 m

Angular displacement of the ball $\Theta =30^{\circ}$

Gravitational potential energy of the ball at the displaced position is equal to $U=mgl(1-cos\Theta )$

Maximum kinetic energy of the ball $Ke=\frac{1}{2}mv^2$

According to energy conservation

$\frac{1}{2}mv^2=mgl(1-cos\Theta )$

$v=\sqrt{2gl(1-cos\Theta )}=\sqrt{2\times 9.8\times 30\times (1-cos30^{\circ})}=8.875m/sec$

So velocity will be equal to 8.88 m/sec
