Answer:
d. catapulting
Step-by-step explanation:
A projectile is a body which moves under the influence of gravitation and its momentum. Examples are: a thrown stone, a thrown javelin, a kicked ball etc. The motion that a projectile has during its flight is called a trajectory motion. While catapulting implies the launch of an object so that it turns to a projectile during its motion.
When a bump or jolt causes a worker or an object to be ejected from a lift, the worker or object undergoes a trajectory motion. Thus, the worker can be referred to as a projectile during the ejection. So that catapulting of the worker occurs in the process.
