Two identical masses are moving down a slope one masses traveling twice as fast as the other mass how does the kinetic energy of

GaryK [48]

Answer:

One mass's kinetic energy is 4 times the other.

Step-by-step explanation:

The formula for kinetic energy is $KE=\frac{1}{2}mv^2$

Where

KE is the kinetic energy

m is the mass

v is the velocity

Now, let mass of the first be m (second is identical so mass of 2nd is m as well)
Let velocity of the first one be v. Since 2nd one is travelling twice as fast, its velocity will be 2v

KE of 1st mass is:

$\frac{1}{2}mv^2$

KE of 2nd mass is:

$\frac{1}{2}m(2v)^2\\=\frac{1}{2}m(4v^2)\\=\frac{1}{2}mv^2 * 4$

Hence, the kinetic energy of the 2nd mass is 4 times the first.

If f(x)=3x^2+2 and g(x)=x^2-9 find (f-g)(x)

miss Akunina [59]

Here given, $f(x) = 3x^2+2$ and $g(x) = x^2-9$

we have to find $(f-g)(x)$ which means the subtracting of the functions f(x) and g(x).

$(f-g)(x) = f(x) - g(x)$

= $(3x^2+2) - (x^2-9)$

= $3x^2+2 -x^2-(-9)$

= $3x^2-x^2+2+9$ ( we know that multiplication of negative and negative is positive)

= $2x^2+2+9$

= $2x^2+11$

We have got the required answer here.

$(f-g)(x) = 2x^2+11$
