A hot air balloon is traveling vertically upward at a constant speed of 4.5 m/s. When it is 28 m above the ground, a package is
ella [17]

Answer:

1.97 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.8 m/s²

s=ut+\frac{1}{2}at^2\\\Rightarrow 21=4.5t+\frac{1}{2}\times -9.8\times t^2\\\Rightarrow 21=-4.5t-4.9t^2\\\Rightarrow 4.9t^2+4.5t-28=0\\\Rightarrow 49t^2+45t-280=0

Solving the above equation we get

t=\frac{-45+\sqrt{45^2-4\cdot \:49\left(-280\right)}}{2\cdot \:49}, \frac{-45-\sqrt{45^2-4\cdot \:49\left(-280\right)}}{2\cdot \:49}\\\Rightarrow t=1.97, -2.89

So, the time the package was in the air is 1.97 seconds

Based on the graph, which data point is most likely to have experimental
Len [333]

Answer:

B. 59 kg

Explanation:

From the graph you notice that a linear relation in indicated by the line joining the points such that the points on the line represent the data that show a correct relationship in the experiment.

This means that the point outside the line has an error .

This point is the value 59 kg that does not align with other values which are included in the graph.

A cubic tank holds 1,000.0 kg of water. what are the the dimensions of the tank in meters? explain your reasoning
Scilla [17]

Given: A cubic tank holds 1,000.0 kg of water.

Mass of water in tank (m) = 1000.0 kg

Density of water (d) = 1000.0 kg /m³

Concept: Volume(V) = Mass / Density

Since the tank holds these water in it so the volume of water will be equal to the volume of the tank.

Hence, the volume of the tank = Mass of water / Density of water

or,                                         =  1000.0 kg / 1000.0 kg m⁻³

or,                                       = 1.0 m³

Since tank is cubical in shape. Let its side be 'x'

The volume of tank (x³) = 1.0 m³

or.          side of tank (x) = 1.0 m

Hence, the dimensions of the tank will be 1.0 m.

While riding in a hot air balloon, which is steadily decreasing at a speed of 1.14 m/s, you accidentally drop your cell phone. H
Ilia_Sergeevich [38]

Answer:

The distance covered by the balloon is 47.52 meters.

Explanation:

Given that,

Initial speed of the balloon, u = 1.14 m/

Let us assumed we need to find the distance covered by the balloon after t = 3 second. Let d is the distance covered by the balloon. It can be given by :

d=ut+\dfrac{1}{2}at^2

Here, a = g

d=ut+\dfrac{1}{2}gt^2

d=1.14\times 3+\dfrac{1}{2}\times 9.8\times (3)^2

d = 47.52 meters

So, the distance covered by the balloon is 47.52 meters. Hence, this is the required solution.
