Calculate the kinetic energy of a 4 kg object moving at 10 m/s.
a 200 J
b 20 J
C 400 J
d 800 J

Sagot :

Answer:

K.E = 200J

Explanation:

  • Kinetic Energy = [tex]\frac{1}{2}[/tex][tex]mv^{2}[/tex]

here m = mass and v = velocity of moving object

where m = 4kg and v =10m/s

=> K.E = 1/2(4*10^2)

=> K.E = 1/2(4*100)

=> K.E = 400/2

=> K.E = 200J
