A Beyblade is a commercial line of a toy tops. It is spun using a rack (ripcord) and a pinion gear inside the launcher. If the ripcord length is 270 mm and it leaves the launcher for 3 seconds and the diameter of the gear is 20mm. Find the rotational speed of the Beyblade top.  If the Beyblade stopped rotating after 2 mins, what is the angular deceleration?

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
