what is the kinetic energy of a ball with a mass of 5 kg rolling at 10 m/s
To find the kinetic energy of an object, you need to use the formula:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
In this case, you have the mass (m) of the ball, which is 5 kg, and the velocity (v) at which it is rolling, which is 10 m/s.
To calculate the kinetic energy:
1. First, square the velocity: 10 m/s * 10 m/s = 100 m^2/s^2.
2. Next, multiply the squared velocity by half of the mass: 1/2 * 5 kg * 100 m^2/s^2 = 250 Joules.
Therefore, the kinetic energy of the ball is 250 Joules.
To calculate the kinetic energy (KE) of an object, you can use the formula:
KE = (1/2) * m * v^2
Where:
KE = kinetic energy
m = mass of the object
v = velocity of the object
In this case, you have a ball with a mass of 5 kg rolling at a velocity of 10 m/s. Using the formula, you can substitute the values:
KE = (1/2) * 5 kg * (10 m/s)^2
Simplify the equation:
KE = (1/2) * 5 kg * 100 m^2/s^2
Multiply the numbers:
KE = 250 kg * m^2/s^2
So, the kinetic energy of the ball is 250 kg * m^2/s^2.
