To express momentum and kinetic energy in terms of mass (m) and velocity (v), we can use the following formulas:

i) Momentum: Momentum is defined as the product of mass and velocity. Therefore, the expression for momentum (p) can be written as:

p = m * v

ii) Kinetic Energy: Kinetic energy is defined as the energy possessed by a moving object due to its motion. The expression for kinetic energy (KE) can be written as:

KE = (1/2) * m * v^2

Now, to calculate the mass and velocity of a ball using these expressions, we would need additional information or data. We cannot directly determine the values without specific measurements or given values.

If you have the values for momentum or kinetic energy, you can rearrange the respective equations to solve for mass (m) and velocity (v).

For example, if you know the momentum (p), you can rearrange the formula for momentum and solve for mass (m):

m = p / v

Similarly, if you know the kinetic energy (KE), you can rearrange the formula for kinetic energy and solve for mass (m) or velocity (v):

m = (2 * KE) / v^2
v = sqrt((2 * KE) / m)

By plugging in the known values for momentum or kinetic energy, you can calculate the corresponding mass and velocity of the ball.
