The force used to kick the ball is 1000N

The mass of the ball is 0.8 kg

Time is 0.8 seconds

Therefore the velocity can be calculated as follows

F= Mv-mu/t

1000= 0.8(v) - 0.8(0)/0.8

1000= 0.8v- 0.8/0.8

Cross multiply both sides

1000(0.8) = 0.8v

800= 0.8v

divide both sides by the coefficient of v which is 8

800/0.8= 0.8v/0.8

v= 1000m/s

Hence the velocity is 1000m/s

Answer:

1000 m/s

Explanation:

From the question given above, the following data were obtained:

Force (F) = 1000 N

Mass (m) = 0.8 Kg

Time (t) = 0.8 s

Velocity (v) =?

Next, we shall determine the the acceleration of the ball. This can be obtained as follow:

Force (F) = 1000 N

Mass (m) = 0.8 Kg

Acceleration (a) =?

F = ma

1000 = 0.8 × a

Divide both by 0.8

a = 1000 / 0.8

a = 1250 m/s²

Finally, we shall determine the velocity. This can be obtained as follow:

Time (t) = 0.8 s

Acceleration (a) = 1250 m/s²

Velocity (v) =?

a = v/t

1250 = v / 0.8

Cross multiply

v = 1250 × 0.8

v = 1000 m/s

Therefore, the ball will move with a velocity of 1000 m/s.

Although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.

<h3>What is the transmission spectrum?</h3>

The transmission spectrum indicates the light portion having a given wavelength that can be passed through a filter.

This spectrum (transmission spectrum) depends on the physical separation of the particles that form the filter.

In conclusion, although the video is not found here, the sentence makes reference to the transmission spectrum of colored filters.

The radius of a sphere is increasing at a rate of 4 mm/s. How fast is the volume increasing when the diameter is 60 mm?
jok3333 [9.3K]
V = [4/3]π r^3 => [dV / dr ] = 4π r^2

[dV/dt] = [dV/dr] * [dr/dt]

[dV/dt] = [4π r^2] * [ dr/ dt]

r = 60 mm, [dr / dt] = 4 mm/s

[dV / dt ] = [4π(60mm)^2] * 4mm/s = 180,955.7 mm/s
