Best blade angle?
the best angle is "45 degree" because the air speed coming out of the fan is giving by this equation V=v.tanθ were : V: air speed,,, v: is the blades speed and we got the maximum of the speed by making the angle 45
The speed of ball increases as it rolls down an inclinem What happens to its speed on a smooth horizontal surface?
It's speed will reduce to to friction by gravity.
How does drag work?
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
What is the horizontal velocity of 25 degrees?
Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case).

How will the angle of a ramp affect the speed of a car going down it?
The larger the angle of the ramp, the faster the car will go down it.
