Yes.
voko said:No. Total mechanical energy at any point = total mechanical energy at the top.

I think you are using two variables for the same thing, mass of the system: ## m = M ##. Use just one for simplicity. Then, why do you have *2 in the final equation, which you did not have in the equation for ##E_K##? ##E_K## already includes the energy of both wheels.
adjacent said:m=M/2 So linear kinetic energy + rotational kinetic energy
Rotational kinetic energy is ##\frac{Mv^2}{2}##
And you said m =M/2
adjacent said:Oh.My problem is solved now.Did you have all this in mind from the beginning? or Did you solve the problem at first?

Fall speed based on angle refers to the rate at which an object falls to the ground when dropped from different angles. This can be affected by factors such as air resistance and gravity.
The angle at which an object is dropped can greatly affect its fall speed. When dropped at a 0° angle, the object will experience the maximum force of gravity and will fall straight down at a constant speed. At a 45° angle, the object will have a combination of vertical and horizontal motion, resulting in a slower fall speed. At a 90° angle, the object will experience the least amount of force from gravity and will have a slower fall speed due to increased air resistance.
Yes, the weight of an object can affect its fall speed based on angle. Heavier objects will generally fall faster at a 0° angle due to the increased force of gravity, while lighter objects may fall slower. However, at a 45° or 90° angle, the weight of the object may have less of an impact on fall speed as air resistance becomes a more significant factor.
Air resistance can greatly affect fall speed based on angle. As an object falls, it will experience air resistance, which increases with the surface area of the object. This means that at a 0° angle, the object will have a smaller surface area and will fall faster due to less air resistance. At a 90° angle, the object will have a larger surface area and will experience more air resistance, resulting in a slower fall speed.
Understanding fall speed based on angle is important in various fields such as physics, engineering, and sports. In physics, it can help predict the motion of objects and in engineering, it can be used to design structures that can withstand different angles of impact. In sports, it can be useful for athletes to understand the trajectory of objects, such as a baseball or football, to improve their performance.
