A drunk college student decides to try to do a perfect swan dive from his apartment window into the pool below. The edge of the pool is 5 meters from the base of the building and his window is on the 3rd floor, which is 8 meters from the ground. If he jumps out the window horizontally at a speed of 4 m/s, does he make it into the water or..

Answers

Answer:

He barely makes it but hit his leg on the pool edge.

Explanation:

Using kinematic formula: Δx=[tex]v_{0}t+(1/2)at^2[/tex]

We can plug in delta x, v zero, and acceleration.

delta x = 8 meters, v0 = 0. a = 9.8

8=(1/2)9.8*t^2

Around 1.278 seconds of airtime.

4 * 1.278 = 5.112 meters horizontally assuming no air resistance

What aspect of motion can you conclude is common among freely falling objects ?

Answers

Answer:

Free-fall is defined as the movement where the only force acting on an object is the gravitational force.

By the second Newton's law, we have that:

F = m*a

Where F = Force, m = mass, a = acceleration.

We can write this as:

a = F/m

And the gravitational force can be written as:

F = (G*M/r^2)*m

Where G is the gravitational constant, M is the mass of the Earth in this case, and r is the distance between both objects (the center of the Earth and the free-falling object)

As the radius of the Earth is really big, the term inside the parentheses is almost constant in the region of interest, then we can write:

G*M/r^2 ≈ g

And the gravitational force is:

F = g*m

And by the second Newton's law we had:

a = F/m = (g*m)/m = g

a = g

Then the acceleration does not depend on the mass of the object.

Then the thing that is common among the free-falling objects is the vertical acceleration.

distance travelled by a train is 495 km in 4 hours 30 minutes, what is its speed in m/s? 

Answers

Answer:

9.09m/s

Explanation:

Speed = Distance/Time

Distance = 495km

Time = 4 hr 30 min = 4 hr 1/2hr = 4.5 hr

Therefore, Speed = 495/4.5 = 110km/h

Now to convert km/h to m/s

110 x 1000/ 110 x 110

110 cancels out each other, we are now left with

1000/110 = 9.09m/s

Displacement of Tiny : 8m (left) - 6m (right) + 2m (left) = 4 meters to the left

Explanation :

Distance : sum of all values of movement given in the question = 8 meters (left) + 6 meters (right) + 2 meters (left)

We have to describe how the atoms of a solid differ from the atoms of a liquid.

What is Atom?

An Atom smallest unit into which matter can be divided without the release of electrically charged particles.

According to the question, the following differences exists between the atoms of solids and liquids -

In solids the atoms are tightly packed while in liquid they are loosely packed.In solids the density of atoms within a specific volume is very high while in liquid it can be either high or low.In solids, atoms are not free to move and they can only oscillate about their mean position while in liquid the atoms are free to move.

Hence, it can be seen that the atoms of solids and liquids are quite different from each other.

The gravitational acceleration on Earth is 9.8 m/s2. What is the weight of a car on Earth (to the nearest whole number) if it has a mass of 1360 kg? 14 N 139 N 1333 N 13,328 N

Answers

Weight = (mass) x (gravitational acceleration where the mass is)

Weight = (1360 kg) x (9.8 m/s²)

Weight = 13,328  kg-m/s²

That's 13,328 Newtons

Given:-

Mass (m) of the car = 1360 kgAcceleration due to gravity (g) = 9.8 m/

To Find: Weight (W).

We know,

W = mg

where,

W = Weight,m = Mass &g = Acceleration due to gravity.

Thus,

W = (1360 kg)(9.8 m/s²)

→ W = 13,328 N (D)

7. The technology they had in the 70's was similar to a modern day _______________ that could fit in our pocket. (space science; The Farthest: Voyager in Space Viewing Guide)

Answers

Answer:

Key Fob.

Explanation:

On the 5th of September, 1977, the National Aeronautics and Space Administration (NASA) launched a spacecraft known as "Voyager 1" to study and explore the outer planets of the solar system.

Additionally, two voyager spacecraft were built for the above mentioned study and exploration exercise; Voyager 1 and Voyager 2. Voyager 2 was actually the first spacecraft while Voyager 1 was launched sixteen (16) days after and was faster.

According to Rich Terrile, the technology they had in the 70's was similar to a modern day Key Fob that could fit in our pocket because the processing power of the computer chip found in a Key Fob was comparable to the much larger voyager probe (Voyager 1 and Voyager 2) of the 70's, that was tagged an artificial brain.

This ultimately implies that, the computer chip found in a car Key Fob is more powerful and sophisticated than the Voyager probe, even though the Key Fob is smaller but having the same amount of memory.

Robin jogs with an average speed of 5.5 m/s for 3.3s.
What was her distance travelled in meters?

Answers

Answer:

18.15m

Explanation:

Speed * Time = Distance

5.5 * 3.3 = 18.15m

The distance traveled by Robin is equal to 18.15 m with an average speed of 5.5 m/s for 3.3s.

What is the average speed?

The average speed can be explained as the total distance covered by the object in a definite time. The average speed can be considered a scalar quantity as it exhibits magnitude and no direction.

The average speed of a physical system can be determined from the ratio of the total distance traveled by the system to the time taken to cover that distance.

The average speed equation of a physical system can be written as follows:

Average speed =  Total distance/total time taken

Given, the average speed of the Roin, = 5.5 m/s

The time is taken by Robin for jogging = 3.3 s

The average speed of the Robin can be determined as:

Average spped = Distance/ time

5.5 = Distance/3.3

Distance traveled by Robin = 5.5 × 3.3 = 18.15 m
