A car has mass 1500 kg and is traveling at a speed of 35 miles/hour. what is its kinetic energy in joules? (Be sure to convert m

photoshop1234 [79]

Answer:

Factor by which kinetic energy increase = 4 times

Step-by-step explanation:

Given,

Mass of the car, v1 = 1500 kg

initial speed of car = 35 miles/h

$=\dfrac{35\times 1609.34}{3600}\ m/s$

= 15.64 m/s

Initial kinetic energy of the car is given by,

$k_1\ =\ \dfrac{1}{2}.m.v_1^2$

$=\ \dfrac{1}{2}\times 1500\times (15.64)^2\ joule$

= 183606.46 J

Final velocity of car v2 = 70 miles/hour

$=\dfrac{70\times 1609.34}{3600}$

= 31.29 m/s

So, final kinetic energy of car is given by

$k_2\ =\ \dfrac{1}{2}.m.v_2^2$

$=\ \dfrac{1}{2}\times 1500\times (31.29)^2$

= 734425.84 J

Now, the ratio of final to initial kinetic energy can be given by,

$\dfrac{k_2}{k_1}=\ \dfrac{734425.84}{183606.46}$

$=>\ k_2\ =\ 4k_1$

Hence, the kinetic energy will increase by 4 times.

Solve 25n=2×25 for n. You can use a related equation. n = <img src="https://tex.z-dn.net/?f=%5Cfrac%7B2%2A25%7D%7B25%7D" id="Tex

Archy [21]

Answer:

n=2

Step-by-step explanation:

25n=2×25

Divide each side by 25

25n/25=2×25/25

n = 2 * 25/25

n =2

How would I solve for slope on an equation similar to 8x+2y=5?

djyliett [7]

Well make the equation into slope intercept form: y=mx + b and whatever the coefficent is to x will be your slope

8x+2y= 5 can be written as y= (-8/2)x + (5/2) so the slope would be (-8/2)
