Which is the best estimate for the mass of a typical lineman on a high school football team
fgiga [73]

We have that the best estimate for the mass of a typical lineman on a high school football team is

100,000 g=100kg

From the options

1. 100,000 g

2. 100,000 kg

3. 100,000 mg

Generally

A Typical lineman cannot be as small as

100000mg=0.1kg=100g

A Typical linesman cannot be as massive as

100,000kg as that is unrealistic

With the Average Mass of A Typical linesman can be

100,000 g=100kg

In conclusion

The best estimate for the mass of a typical lineman on a high school football team is

100,000 g=100kg
