To determine the new weight of the modified pick-up truck, we need to consider the weight added or removed during the modification process.
Step 1: Determine the weight of the components added or removed
- Weight added for suspension lift kit (varies, but let's estimate around 150 pounds) = + 150 lbs
- Weight removed from body panels (for weight reduction) = - 100 lbs
Step 2: Calculate the net weight change
Net Weight Change = Weight Added - Weight Removed
= 150 lbs - 100 lbs
= +50 lbs
Step 3: Calculate the new weight
New Weight = Original Weight + Net Weight Change
= 4000 lbs + 50 lbs
= 4050 lbs
Therefore, the modified pick-up truck's estimated weight after the modifications would be 4050 pounds.
