Question

find the kinetic energy of a car of 200kg with a speed of 10m/s​

Answer 1

Answer:

10kJ

Explanation:

K.E.=1/2mv²

      =1/2*200*10²

       =100*100

       =10000 J

        =10kJ

pls mark my answer as brainliest

Answer 2

Answer:

Given:

• $Mass = 200 \ kg$
• $v = 10 \ m/s$

Solution:

$\boxed{Kinetic \ energy = \dfrac{1}{2} mv^2}$

$\implies Kinetic \ energy = \dfrac{1}{2 \! \!\! \! ／} \times 200\!\!\!\!\!\!／ ^{100} \times 10$

$\implies Kinetic \ energy = 1000 \ J$
