Measuring weight of the car?

Can anyone help me with this question. i don't really know anything about car. thank you







a. Comment on errors that may arise in the step when you measure the tire's gauge pressure. Estimate the error in your measurement.

b. Comment on errors that may arise in the step when you measure the tire's contact area with the ground.

Do you think the method of using rectangles to approximate area was an underestimate or an overestimate? How then would the force calculation change? Consider the treads of your tires. With all of these considerations, approximate the error in your estimate for the surface area.Measuring weight of the car?a.

Without knowing the type of pressure gauge, it's impossible to estimate the error.



This sounds like a followup to a lab that you performed.

depends on how you do the measurement.

no possible wayMeasuring weight of the car?Two easy methods are:

1. Take the car to the highway scales, where trucks are weighed.

2. Read the vehicle weight in the owners manual.
