Answer:
The angle through which the wheel turned is 947.7 rad.
Explanation:
initial angular velocity, = 33.3 rad/s
angular acceleration, α = 2.15 rad/s²
final angular velocity, = 72 rad/s
angle the wheel turned, θ = ?
The angle through which the wheel turned can be calculated by applying the following kinematic equation;
Therefore, the angle through which the wheel turned is 947.7 rad.
I think it is because the electrons repel each other
This is a diagram from above, the air resistance is oppose to movement, the bird is moving forward given its force is bigger.
Go with the last one because you need potential energy for kinetic energy
