Calculate the kinetic energy of a 1000 kg car traveling at 30 m/s, a typical speed on a
highway.

Respuesta :

The kinetic energy of the car is [tex]4.5\cdot 10^5 J[/tex]

Explanation:

The kinetic energy of an object is the energy possessed by the object due its motion, and it is calculated as

[tex]K=\frac{1}{2}mv^2[/tex]

where

m is the mass of the object

v is its speed

For the car in this problem, we have

m = 1000 kg is its mass

v = 30 m/s is its speed

Substituting, we find the kinetic energy of the car:

[tex]K=\frac{1}{2}(1000)(30)^2=4.5\cdot 10^5 J[/tex]

Hello!

Calculate the kinetic energy of a 1000 kg car traveling at 30 m/s, a typical speed on a  highway.

We have the following data:

m (mass) = 1000 kg

v (velocity) = 30 m/s

KE (kinetic Energy) = ? (in Joule)

Formula to calculate kinetic energy:

[tex]\boxed{KE = \dfrac{1}{2} *m*v^2}[/tex]

Solving:

[tex]KE = \dfrac{1}{2} *m*v^2[/tex]

[tex]KE = \dfrac{1}{2} *1000*30^2[/tex]

[tex]KE = \dfrac{1}{2} *1000*900[/tex]

[tex]KE = \dfrac{900000}{2}[/tex]

[tex]KE = 450000\:J \to \boxed{\boxed{KE = 4.5*10^5\:J}}\:\:\:\:\:\:\bf\green{\checkmark}[/tex]
