Through windtunnel measurements of the air.
In 2010, the Air Force is a part time sponsor for Elliott Sadler in the Nascar Sprint Cup Series.
You cannot calculate force with only speed.
If you count television, fans in the stands, and those in the infield: NASCAR HANDS DOWN!!
It depends on what else you know. If you know the mass and can measure the acceleration, you can use that to calculate force, but there are other ways to calculate force.
Take the weight of the object then divide by however many visible ropes.(if the force is pulling down)
You calculate peak force by multiplying Mass times Velocity divided by time
we say it is a balanced force
no you can not
