hey can anyone help me out in dis pls!

Answer:

64.4 m

Explanation:

First, find how long it takes to land.  Given in the y direction:

Δy = 0 m

v₀ = 27 m/s sin 60° ≈ 23.4 m/s

a = -9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

0 m = (23.4 m/s) t + ½ (-9.8 m/s²) t²

t = 4.77 s

Next, find how far it travels in that time.  Given in the x direction:

v₀ = 27 m/s cos 60° = 13.5 m/s

a = 0 m/s²

t = 4.77 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (13.5 m/s) (4.77 s) + ½ (0 m/s²) (4.77 s)²

Δx = 64.4 m

Answer:

Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.

D. Making improvements to the original prototype in order to perform

more tests

Explanation:

just did it

The one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.

Prototype is defined as a type of early version, or initial release of a product created to test a theory or procedure.

It can be defined as a test procedure where design teams put concepts into concrete forms, whether they be paper or digital.

It can also be defined as a useful tool for the creation of new products. It provides the creative with the opportunity to watch their concept come to fruition.

There are three basic rule of prototyping.

When the EGL system code does not have access to the function itself, a function prototype definition is used to provide type checking on function calls.

Thus, the one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.

Answer:

A velocity is a vector unit, and average velocity can be described as the displacement divided by the time. The units for velocity can be understood from the definition to be meters/second or in common any distance unit over any time unit. The average speed of a body is described as the distance covered divided by the time elapsed.

Explanation:

Answer:

10 m/s

Explanation:

The average velocity is the slope of the graph.

m = (10 - 0)/(1 - 0)

m = 10/1

m = 10 m/s

Explanation:

Answer:

s = 92.36 m

Explanation:

The distance covered by an object moving with uniform speed is given by the following formula:

s = vt

where,

s = distance covered by car during the time when driver was distracted in texting = ?

v = uniform speed of car = (95 km/h)(1 h/3600 s)(1000 m/1 km) = 26.39 m/s

t = time taken by the driver for texting = 3.5 s

Therefore, using these values in equation, we get:

s = (26.39 m/s)(3.5 s)

s = 92.36 m

Multiply field strength (N/kg) by mass (kg) to get weight (N)

At the start, the car is carrying

4.7 kg * (9.8 N/kg) = 46.06 N

At the end, it is carrying

3.0 kg * (9.8 N/kg) = 29.4 N.

Assuming the car remains completely intact, its weight was reduced by

46.06 N - 29.4 N = 16.66 N.

Designing experiments to replicate the conditions in which life may have first evolved on Earth

Explanation:

In 1953, Stanley L. Miller and Harold C. Urey conducted an experiment to prove that life started from inanimate objects. The research was conducted by utilizing proposed chemical substances, mixed together through a scientific design process. The outcome of the research is the predicted atmospheric conditions before the pre-living form started on earth.

Therefore, in this case, the action that might lead scientists to develop new explanations about the universe is "Designing experiments to replicate the conditions in which life may have first evolved on Earth."

Answer: left and applied force

Explanation:

Answer: 1 2 5

Explanation:

Galileo Galilei, an Italian physicist, is credited with being the first to calculate speed by dividing it by the distance traveled and the time required. Galileo defined speed as the distance covered in a predetermined period of time. Thus option A, B. E is correct.

Speed is determined by dividing the distance by the time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is measured in seconds, the units in this example will be meters per second (m/s) (s).

That is speed = distance time. Alternatively, you can calculate the time by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs.

Therefore,  For instance, if a car drives 120 miles (ca. 193 km) in 2 hours, we may calculate the speed as 120 × 2 = 60 miles per hour (ca. 97 km/h).

Given that,

Mass of shark, m = 200 kg

Speed of the shark, v = 15 m/s

We need to find the momentum of the shark. It can be calcullated as follows :

[tex]p=200\ kg\times 15\ m/s\\\\p=3000\ kg-m/s[/tex]

So, the momentum of the shrak is 3000 kg-m/s.

The picture shows the scientific notation

Given :

You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you  travel 250 miles in an hour and a half.

To Find :

Average speed.

Solution :

We know, average speed is given by :

[tex]v=\dfrac{\text{Total distance covered}}{\text{Total time taken}}\\\\v=\dfrac{200+250}{3+1.5}\ miles/hr\\\\v=\dfrac{450}{4.5}\ miles/hr\\\\v=100\ miles/hr[/tex]

Therefore, average speed of the journey is 100 miles/hr.

Hence, this is the required solution.
