The kinetic energy of an object is given by the formula:
KE = 0.5 * m * v^2
Where:
KE = kinetic energy
m = mass
v = velocity
If both the mass and speed of the ball are doubled, the new kinetic energy can be calculated as follows:
New mass = 2m
New speed = 2v
New KE = 0.5 * (2m) * (2v)^2
New KE = 0.5 * 2 * m * 4 * v^2
New KE = 4 * 0.5 * m * v^2
New KE = 2 * KE
Therefore, if both the mass and speed of the ball are doubled, the kinetic energy of the ball will be quadrupled.
