Question

Imagine a 10 kg block moving with the velocity of 30 m/s to the left. Calculate the kinetic energy of this block

Answer 1

4.5 Kj

Step-by-step explanation:

`kinetic energy \: = (1)/(2) m {v}^(2)`

m = 10kg

v = 30m/s

Ek = 1/2(10×30²)

= 5×900

= 4500

= 4.5 Kj

Answer 2

Answer:4500joules
