Question

Calculating kinetic energy 1200kg car moving at 10​

Answer 1

Answer:

60000J

Explanation:

Given parameters:

Mass of car  = 1200kg

Speed  = 10m/s

Unknown:

Kinetic energy  = ?

Solution:

The kinetic energy is given as:

   Kinetic energy  = $\frac{1}{2}$  m v²  

Now insert the parameters and solve;

   m is the mass

    v is the velocity  

 Kinetic energy  =  $\frac{1}{2}$ x 1200 x 10²   = 60000J
