Question

A car of mass 500 kg is moving with a speed of 60 m/s. Find the kinetic energy.​

Answer 1

Answer:

heya

Explanation:

K.E= 1/2 mv^2

= 1/2 *500*3600

= 120000 J

Answer 2

Given:

☛ mass of car, m = 500 Kg

☛ velocity of car, v = 60 m/s

To Find:

☛ Kinetic energy of the car

Solution:

We know,

$</p><p></p><p>\qquad \boxed{ E_{K.E} = \frac{1}{2} mv^{2} } </p><p></p><p>$

Now, Putting the values

$</p><p></p><p>\Rightarrow \quad E_{K.E} = \frac{1}{\cancel{2}} \times \cancel{500} \times 60^{2} </p><p></p><p>\\ \\</p><p></p><p>\Rightarrow \quad E_{K.E} = 250 \times 3600</p><p></p><p>\\ \\</p><p></p><p>\Rightarrow \quad E_{K.E} = 900,000</p><p></p><p>$

Hence, Kinetic Energy of the car is 900 kJ
