A 3.5 m long horizontal rod has two forces applied to it. One on the far left corner with a force of 4N at 60 degrees downward, the other on the far right corner with a force of 10N at 60 degrees downward. There is a pin on the axis of rotation. The force of 4N is 2.5m to the left of the pin and the 10N force is 1.0m to the right of the pin. Determine the magnitude and direction of the force in the pin.
An aeroplane has wings with a surface area of 34 m2. The shape of the wings are such that air moving over the top of them travels 20% faster than the velocity of the air under the wing, what is the take-off speed of the plane

At time t = 0 s, a puck is sliding on a horizontal table with a velocity 3.60 m/s, 35.0° above the +x axis. As the puck slides, a constant acceleration acts on it that has the following components: ax = –0.360 m/s2 and ay = –0.980 m/s2.
How many electrons would need to be transferred in order to balance these two forces?
