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

as shown in the attached figure, a block with mass m₁ is attached to a massless ideal string. the string wraps around a massless pulley and then wraps around a second massless pulley that is attached to block with mass m₂and ultimately attaches to a wall. the whole system is frictionless.

a coordinate system is given in the figure

given the magnitude a₁ of the acceleration of the block with mass m₁ , find a₂, the magnitude of the horizontal acceleration of the block with mass m₂

a₂ = ?

For my assigment, I was asked to design a electric motorbike that has a peformance equal to Honda CBR1000 Fireblade which has a petrol engine. A part of the the assignment is to calculate " An estimate of maximum Power your new motor will need to generate to match the Honda’s performance." I can make the assumption, apart from changing the motor, everything else is going to stay the same so the fairing,the rider and etc they're gonna be the same for the two bikes. So can you please tell me how I can calculate that which information would I need ?
