The formula for calculating force needed to move a system of bodies at 30 ft/s is Force = Mass x Acceleration. In this case, acceleration can be calculated by dividing the velocity (30 ft/s) by the time it takes for the system to move (usually in seconds).
The mass of the system of bodies can be determined by adding up the individual masses of each body in the system. This can be done by using a scale or by looking up the mass of each body in a reference table.
The units for the calculation should be consistent. This means that the mass should be in kilograms (kg) and the acceleration should be in meters per second squared (m/s²). This will result in the force being measured in Newtons (N).
Yes, this formula can be used for systems of bodies moving at different speeds. The velocity (v) in the formula can be changed to match the velocity of the system in question, as long as the units are consistent.
Yes, there are other factors that should be considered when using this formula. Friction, air resistance, and other external forces can affect the calculation of force needed to move a system of bodies. These factors should be taken into account and adjusted for in the calculation if possible.
