Answer:

1] 8500000 = <u>8.5 × 10⁶</u>

2] .000072 = <u>7.2 × 10⁻⁵</u>

3] 5.3 × 10⁴ = <u>53000</u>

4] 2.8 × 10⁻³ = <u>0.0028</u>

5] Velocity = \frac{distance}{time}

 V = \frac{50}{10}

 <u>V = 5 m/s</u>

6] Acceleration = \frac{V1-V2}{time}

 A = \frac{30-15}{3}

 A = \frac{15}{3}

 <u>A = 3 m/s²</u>

A car with a mass of 1500 kg is traveling down the interstate at 25 m/s. What is the kinetic energy of the car, measured in Joul
iren2701 [21]

Answer:

The answer is

<h2>468 , 750 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

KE =  \frac{1}{2} m {v}^{2}

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

KE =   \frac{1}{2}  \times 1500 \times  {25}^{2}  \\  = 750 \times 625

We have the final answer

<h3>468 , 750 J</h3>

Hope this helps you
