Question

What is the kinetic energy of an object that has a mass of 12 kg and moves with a velocity of 10 m/s

Answer 1

Answer:

600 J

Explanation:

The formula to find the kinetic energy of an object is $\frac{1}{2}mV^2$

• m = mass in kg
• V = velocity in m/s
• KE is measured in Joules just as all other forms of energy.

Now, let's plug in the variables we're given and simplify.

• $\frac{1}{2}(12)(10)^2$
• $\frac{1}{2}(12)(100)$
• $(6)(100)$
• $(600)$

Thus, the answer is 600 Joules.

Answer 2

Answer:

600 J

Explanation:

m = 12 kg

v = 10 m/s

KE = 1/2mv²

= 1/2 x 12 x 10 x 10

= 6 x 100

= 600 J
