a 4kg bird is flying with a velocity of 4m/s2. what is the kinetic energy?
KE = m*V^2/2 = 4 * 4^2/2 = 32 Joules.
To calculate the kinetic energy of an object, you need to use the formula:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
Given that the bird has a mass of 4 kg and is flying with a velocity of 4 m/s, we can substitute these values into the formula:
KE = 1/2 * 4 kg * (4 m/s)^2
First, calculate the square of the velocity:
4 m/s * 4 m/s = 16 m^2/s^2
Then, substitute this value into the formula:
KE = 1/2 * 4 kg * 16 m^2/s^2
Next, perform the calculations:
KE = 0.5 * 4 kg * 16 m^2/s^2
KE = 8 kg m^2/s^2
Therefore, the kinetic energy of the 4 kg bird flying with a velocity of 4 m/s is 8 kg m^2/s^2.
To calculate the kinetic energy of an object, we can use the formula:
Kinetic Energy = (1/2) * mass * velocity^2
Given:
Mass of the bird (m) = 4 kg
Velocity of the bird (v) = 4 m/s
Plugging the values into the formula:
Kinetic Energy = (1/2) * 4 kg * (4 m/s)^2
Simplifying the equation:
Kinetic Energy = (1/2) * 4 kg * 16 m^2/s^2
Kinetic Energy = 8 kg * m^2/s^2
Therefore, the kinetic energy of the 4 kg bird flying with a velocity of 4 m/s^2 is 8 Joules (J).
