. . . please?
Now, plugging in the numbers, we get: KE = 1/2 * 1500 kg * (20 m/s)^2. That ends up giving us a kinetic energy of 300,000 joules!
Boom, there you have it! That car has got a serious amount of energy buzzing around. Just remember, kinetic energy won't make the car more stylish or fashionable. Trust me, I've tried.
Kinetic Energy = 1/2 * mass * velocity^2
Let's substitute the given values into the formula:
Mass = 1,500 kg
Velocity = 20 m/s
Plugging these values into the formula, we get:
Kinetic Energy = 1/2 * 1,500 kg * (20 m/s)^2
Now, let's solve the equation step by step:
First, calculate the square of the velocity:
Velocity^2 = (20 m/s)^2 = 400 m^2/s^2
Next, multiply the square of the velocity by the mass of the car:
1/2 * 1,500 kg * 400 m^2/s^2 = 300,000 kg.m^2/s^2
Simplifying further:
300,000 kg.m^2/s^2 = 300,000 Joules
Therefore, the kinetic energy of the car is 300,000 Joules.
