A 1,000 kg car is driving on a 15 m high bridge at 5 m/s. What is the kinetic energy of the car?

A. 0 J
B. 12,500 J
C. 25,000 J
D. 147,000 J

Answer :

Answer:

[tex]KE=12,500J[/tex]

Explanation:

The formula for kinetic energy is:

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

We can plug in the given values into the equation:

[tex]KE = \frac{1}{2}*1000kg*(5m/s)^2[/tex]

[tex]KE = 500kg*25m^2/s^2[/tex]

[tex]KE=12,500J[/tex]
