Question

calculate the kinetic energy of a 2000kg car traveling at 60km/h​

Answer 1

Answer:

277778 J is the correct answer.

Answer 2

Formulas you need to use:

• K=0.5mass(Velocity^2)
• km/h / 3.6 ===>M/S

Step 1:

convert km/h to m/s : 90/3.6 = 25m/s

Step 2:

Put the values in the formula : K=0.5*1000*(25^2)= 500*625= 312500 joules.
