5 0

Answer:

Explanation:

1)Solution,

Distance(s)=30m

Time taken(t)=11s

Now,

Average velocity=s/t=30m/11s=2.72m/s

2)Solution,

Distance(s)=20km=20x1000m=20000m

Time(t)=9:30-8:30=1:30=60+30 min=90min=90x60=5400s

Now,

Average velocity=s/t=20000m/5400s=3.7m/s

Preston tossed a red ball upward and it reaches a maximum height of 3.0. What is the final velocity when it returns to prestons
Leokris [45]
That will depend on the units of the 3.0. We need to know if it's 3 feet, 3 yards, 3 meters, or 3 miles. Each one will have a different answer.

Suppose that a car starts from rest at t = 0. The car moves with an acceleration of 1.5 m/s2. How far will the car travel in 3.0
rodikova [14]

Answer:

6.75m

Explanation:

To calculate the distance in this question, we can use the formula:

S = ut + 1/2at^2

Where; S = distance

u = initial velocity = 0m/s

t = 3s

a = 1.5m/s^2

Hence:

S = (0 × 3) + 1/2 (1.5 × 3 × 3)

S = 0 + 1/2 (13.5)

S = 13.5/2

S = 6.75

Therefore, the car will travel 6.75m in 3seconds.

A shell of mass m and speed v explodes into two identical fragments. If the shell was moving horizontally (the positive x direct
-Dominant- [34]

Answer:

The velocity of the other fragment immediately following the explosion is v .

Explanation:

Given :

Mass of original shell , m .

Velocity of shell , + v .

Now , the particle explodes into two half parts , i.e  \dfrac{m}{2} .

Since , no eternal force is applied in the particle .

Therefore , its momentum will be conserved .

So , Final momentum = Initial momentum

mv=\dfrac{mv}{2}+\dfrac{mu}{2}\\\\u=v

The velocity of the other fragment immediately following the explosion is v .

How does the jet stream affect the movement of air masses
ryzh [129]

Answer:

See the explanation below.

Explanation:

Jet streams are defined as the fast flowing meandering air currents in the atmosphere, they generally flow around ten kilometers from above the Earth's  surface and form at the boundaries of two air masses which have significant temperature difference within them, greater the temperature difference more significant and fast flowing will be the jet streams. Jet streams have a key role in determining the weather of given region as it separates warmer air mass with the colder air mass and hence move the weather system to new areas and sometimes it even stops at any particular place therefore determining or affecting the weather condition of the region. Depending upon seasons and other factors such as position of sun these jet streams also shift their patterns, for example, Weather and climatic condition of United Kingdom is largely affected by the movement of these Jet streams.
