Define the term kinetic energy. A 20 kg toolbox fell vertically from the roof of a building. It took the toolbox 2.5 seconds to reach the ground. Calculate: \( \begin{array}{ll}3.2 .1 & \text { The height from which the toolbox fell with reference to the ground } \\ 3.2 .2 & \text { The velocity with which the toolbox hit the ground } \\ 3.2 .3 & \text { The momentum of the toolbox as it hits the ground }\end{array} \)
