In the UK, the maximum legal speed for a pellet fired from an airgun is 184 m s–1.
The diagram shows a suspended block of wood used in a school laboratory to determine the speed of an airgun pellet.
A pellet is fired from the airgun into the block of wood, as shown above.
The pellet stays in the block of wood. The block of wood and pellet together then move along the path shown. The maximum height reached is measured.
In a particular experiment, the maximum height reached is 6.0 cm.
mass of pellet = 0.93 g
mass of pellet and block of wood together = 150 g
