Explanation:
6000 - 6 = 5994 is the difference in their values
We have that the best estimate for the mass of a typical lineman on a high school football team is
From the options
1. 100,000 g
2. 100,000 kg
3. 100,000 mg
Generally
A Typical lineman cannot be as small as
A Typical linesman cannot be as massive as
as that is unrealistic
With the Average Mass of A Typical linesman can be
In conclusion
The best estimate for the mass of a typical lineman on a high school football team is

Answer:
The speed at the end of the track = 27 m/s
The acceleration = 1.2 m/s²
Please find the Δx vs Δt, v vs Δt, a vs Δt
Explanation:
We have;
x = u·t + 1/2·a·t²
Where;
x = The distance = 300 m
u = The initial velocity = 0 m/s (Ball at rest)
t = The time taken = 22.4 s
Therefore;
300 = 0 + 1/2×a×22.4²
a = 2×300/22.4² = 1.19579 ≈ 1.2 m/s²
v = u + a×t
∴ v = 0 + 1.2 × 22.4 = 26.88 ≈ 27 m/s
Part of the table of values is as follows;
t, x, v
0, 0, 0
0.4, 0.095663, 0.478316
0.8, 0.382653, 0.956632
1.2, 0.860969, 1.434948
1.6, 1.530611, 1.913264
2, 2.39158, 2.39158
2.4, 3.443875, 2.869896
2.8, 4.687497, 3.348212
3.2, 6.122445, 3.826528
3.6, 7.748719, 4.304844
Answer:8.68 m/s
Explanation:
Given
If the height of vault is h=4.85 m
her center of mass is 1 m above ground
Net height h=3.85 m
conserving energy
