Calculate the kinetic energy of a tennis ball with a mass of 58g served by Andy Murray at 58 m/s
1/2 * m * v^2 = 1/2 * .058 * 58
answer is in Joules
To calculate the kinetic energy of an object, you can use the formula:
Kinetic energy (KE) = 0.5 * mass * velocity^2
However, it is important to ensure that the mass is in kilograms and the velocity is in meters per second. Let's convert the given mass of the tennis ball from grams to kilograms:
Mass of the tennis ball = 58g = 0.058 kg
Now we can calculate the kinetic energy:
KE = 0.5 * 0.058 kg * (58 m/s)^2
KE = 0.5 * 0.058 kg * 3364 m^2/s^2
KE = 98.704 Joules
Therefore, the kinetic energy of the tennis ball served by Andy Murray is approximately 98.704 Joules.
