Question

A car is traveling at a velocity of 10m/s and mass of 250kg find kinetic energy​

Answer 1

Answer:

the question is quite basic

the formula for kinetic energy is

1/2mv²

we have

m=250kg

v=10m/s

taking the values in the formula we get

250×(10²)/2

250×100/2

now converting 250 kg in grams we get

250×1000

250000

thus 250000/2

125000joule is the required answer

Answer 2

Answer:

The correct answer is equal to 12500J.

Explanation:

The velocity of the car is equal to 10m/s.

The mass of the car is equal to 250kg.

The kinetic energy is directly proportional to the mass of an object.

The kinetic energy is directly proportional to the square of the velocity of an object.

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

KE is denoted by the kinetic energy of an object.

m denoted as a mass of an object.

v denoted as a velocity of an object.

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

$KE=\frac{1}{2}250$×$10^{2}$

KE = 12500J

So, the kinetic energy of the car is equal to 12500J.
