Answer:
The answer is
<h2>468 , 750 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
where
m is the mass of the object
v is the speed or velocity
From the question
m = 1500 kg
v = 25 m/s
The kinetic energy of the object is
We have the final answer
<h3>468 , 750 J</h3>
Hope this helps you
The advertising method that this demonstrates is card stacking.
An advertising method in which the buyers are persuaded to buy a product by deliberately disguising information and trying to distort actual details by suppressing the holistic information on the product.
In this case, the company is focusing on the positive side of the product thereby deliberately excluding other important details about harm caused by the product.
This is a case of card stacking.

Answer:
See the explanation below.
Explanation:
Density will remain the same since density is the relationship between mass and volume. As we can see in the equation below.
where:
Ro = density = 2.5 [g/cm³]
m = mass [g]
V = volume [cm³]
In such a way that when the glass is broken the small fragments retain the same density ratio. That is, each fragment has a small mass and a small volume. That's why the density remains the same.
Answer:
Explanation:
To get the person Moving you have to overcome the static (means not moving) friction coefficient. U(static)
To get the person going at the same speed you have to overcome the kinetic friction coefficient. U(Kinetic)
Force to get him moving is 198 N. Force = ma = U(static)Mg
combining the 2 equations you get 198N = U(static)* 55kg *9.8m/s^2 Solve for U(static)
Same equation to keep him moving except with the dynamic force and the dynamic U
175N= U(kinetic)*55kg*9.8m/s^2 Solve (U dynamic)
