Bullet of mass 30g travels at a speed of 1500m/s,calculate its kinetic energy.
KE = 0.5M*V^2 = 0.5*0.03*(1500)^2 = 33,750 J.
Oh, don't worry, I got this one! Let me calculate the kinetic energy for you. Now, first things first, we need to convert the mass of the bullet from grams to kilograms. So, 30 grams is equal to 0.03 kilograms. Got it? Great!
Now, let's use the formula for kinetic energy: KE = 1/2 * mass * velocity squared. Plugging in the values we have, we get KE = 1/2 * 0.03 kg * (1500 m/s)^2.
Now, we just need to do some math. Let me grab my calculator... *beep boop beep* Okie-dokie, the answer is 675 joules.
So, the kinetic energy of the bullet is 675 joules. Keep in mind that this calculation assumes there's no air resistance and all that, but we'll just ignore that for now. Cheers!
The kinetic energy of an object can be calculated using the formula:
Kinetic Energy (KE) = (1/2) * mass * velocity^2
Given:
mass = 30g = 0.03 kg (since 1 kg = 1000 g)
velocity = 1500 m/s
Substituting the values into the formula, we get:
KE = (1/2) * 0.03 kg * (1500 m/s)^2
Simplifying the equation:
KE = 0.5 * 0.03 kg * 2250000 m^2/s^2
Now, calculating the result:
KE = 33750 Joules
Therefore, the kinetic energy of the bullet is 33750 Joules.
To calculate the kinetic energy of the bullet, we can use the formula:
Kinetic Energy = 1/2 * mass * velocity^2
Given that the mass of the bullet is 30g and its velocity is 1500m/s, we need to convert the mass to kilograms first since the formula requires the units to be in kg:
30g = 30/1000 kg = 0.03 kg
Now, we can substitute the values into the formula:
Kinetic Energy = 1/2 * 0.03 kg * (1500 m/s)^2
Calculating further:
Kinetic Energy = 0.5 * 0.03 kg * 2250000 m^2/s^2
Kinetic Energy = 33750 joules (J)
Therefore, the kinetic energy of the bullet is 33750 joules.
