Answer:

20 s

Explanation:

Impulse = change in momentum

F Δt = m Δv

100 N Δt = 20 kg × (100 m/s − 0 m/s)

Δt = 20 s

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

Which of the following exhibits parabolic motion?
harina [27]
Parabolic Motion<span> of Projectiles. A projectile is an object upon which the only force is gravity. Gravity, being a downward force, causes a projectile to accelerate in the downward direction.

So I would say that the best answer provided is C. a leaf falling from a tree because the downward force of gravity  causes the leaf to accelerate in the downward direction</span>

John throws a ball with a velocity of 30 m/s at an angle of 60 degrees. What is the horizontal component of the velocity?
umka21 [38]

The horizontal component of the velocity is equal to: D. 15 m/s.

<u>Given the following data:</u>

  • Velocity = 30 m/s
  • Angle = 60°

To determine the horizontal component of the velocity:

The horizontal component of the velocity represents the influence of velocity  in displacing an object or projectile in the horizontal direction.

Mathematically, the horizontal component of velocity is given by the formula:

V_x = Vcos(\theta)

Substituting the given parameters into the formula, we have;

\\\\V_x = 30cos(60)\\\\V_x = 30 \times 0.5

Horizontal component, Vx = 15 m/s
