Calculate the kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph. (1 mile = 1.6093 km, 1 lb = 45
victus00 [196]
<span>Let's convert the speed to m/s: speed = (55 mph) (1609.3 m / mile) (1 hour / 3600 seconds) speed = 24.59 m/s Let's convert the mass to kilograms: mass = (2135 lb) (0.45359 kg / lb) mass = 968.4 kg We can find the kinetic energy KE: KE = (1/2) m v^2 KE = (1/2) (968.4 kg) (24.59 m/s)^2 KE = 292780 joules The kinetic energy of the automobile is 292780 joules.</span>

A car drives 215 km east and then 45 km north. What is the magnitude of the car’s displacement? Round your answer to the nearest
34kurt

Displacement = (straight-line distance between the start point and end point) .

Since the road east is perpendicular to the road north,
the car drove two legs of a right triangle, and the magnitude
of its final displacement is the hypotenuse of the triangle.

    Length of the hypotenuse = √ (215² + 45²)

                                              =  √ (46,225 + 2,025)

                                              =   √ 48,250

                                              =       219.7 miles .

The end of Hubbard Glacier in Alaska advances by an average of 105 feet per year.
kow [346]

Answer:

Speed of the glacier, v=1.0148\times 10^{-6}\ m/s

Explanation:

Given that,

The average speed of Hubbard Glacier, v=105\ feet/year

We need to find speed of advance of the glacier in  m/s. As we know that,

1 meter = 3.28 feet

And

1\ year=3.154\times 10^7\ second

Using the above conversions, we can write the value of average speed is :

v=1.0148\times 10^{-6}\ m/s

So, the speed of advance of the glacier is 1.0148\times 10^{-6}\ m/s. Hence, this is the required solution.

A standard object defined as having a massof exactly 7.98 kg is given an acceleration of2.5244 m/s2when a certain force is appli
Gnom [1K]

Answer:

m' = 20.1024 kg

Explanation:

Given that for standard object

m = 7.98 kg

a= 2.5244 m/s²

From Second law of Newtons

F= m a

Now by putting the values

F = 2.5244 x 7.98 N

F= 20.144 N

In second object

F'= m ' a'

F' = F  ( given that)

20.144 = 1.0021 m'

m' = 20.1024 kg
