Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

A ball of mass 2 kilograms is attached to a
rope of length 3 meters. The ball swings
along a vertical circular path as shown in
Figure 2. Only two forces
weight – act on the ball. As the ball swings
around, it travels slowest at the top and
- tension and
fastest at the bottom.

The rope can withstand a maximum tension of 150 N. What is the maximum speed that the
ball can have at the bottom of the circle (point B) before the rope breaks?
