A ball, of mass 0.1 kg, is dropped from a height of 12 m, What is its momentum when it stikes the ground, in kg m/s?
You need to remember the formula of momentum such that:
`p = m*v`
You should use the kinematic equation that helps you to find the velocity such that:
`v^2 = v_0^2 + 2a*x`
Since the initial velocity is...
