If you were called upon to balance a meter stick on the palm of your hand, vertically, with a sliding weight attached, where would you place the sliding weight so that it would be easiest to keep the stick from rotating,ie: keep it balanced? [ 1) at the lowest point on the stick, 2) near the middle of the stick, or 3) near the end away from your hand ] . Explain

A meter stick is held vertically above your hand, with the lower end between your thumb and first finger. On seeing the meter stick released, you grab it with these two fingers. You can calculate your reaction time from the distance the meter stick falls, read directly from the point where your fingers grabbed it. If the measured distance is 18.3 cm, what is the reaction time?

Torques and Center of Mass. The
Experiment:
In this experiment, you balance a meter stick, to balance the
meter stick, attach masses at positions until the system is in
equilibrium.
The meter stick acts as if all its mass was concentrated at its
center of mass. With the fulcrum at the center of mass, r (the
distance from the axis of rotation to the place where the force is
applied) is 0, so there’s no torque due to the meter...

Required (hand in) 1. By using a 2-meter stick (like the one in lab) marked in millimeters and a stopwatch that measures to 1/100h of a second, you decide to measure the speed of a motorized toy car that travels at a constant velocity. You measure out a 162.0cm interval with the 2-meter stick and time how long it takes the car to travel that distance using the stopwatch. Repeating the experiment 5 times you get the following time data:...

Consider a person holding a bag like in the diagram, palm facing
upwards, forearm parallel to the floor, and upper arm making a
right angle with their forearm. Masses are added to the bag until
the subject can no longer comfortably keep the angle between their
upper arm and forearm at 90 degrees.

For your balance sheet, you want to calculate the asset side (left hand side) and then total liabilities from the right-hand side. Then place in the owner’s equity number that balances both sides. So, place in the owner’s equity number last after you have calculated the assets on the left-hand side and total liabilities on the right-hand side. The top left-hand side will include all Current Assets. Below that will include Net Fixed assets. Then total them up to come...
