Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

100%

Small mass B on a rotating table is constant tangential acceleration as shown in the figure.
It starts from zero initial velocity under its effect and rotates rapidly. With block B
Since the friction coefficient between the table is µ = 0.6, the block will be 5.4 km / h without slipping.
Calculate the shortest time interval that can reach the speed?
