Question

Calculate the kinetic energy of a 4 kg object moving at 10 m/s.

Answer 1

Answer:

K.E = 200J

Explanation:

• Kinetic Energy = $\frac{1}{2}$$mv^{2}$

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
