b) Lifting heavy objects
c) Aerobic exercise
d) Running at high speed

Calculate the compressional force on the fifth lumbar vertebra if the mass is 80 kg and the acceleration due to gravity is 9.8m/s^2:
a) 784 N
b) 160 N
c) 8.16 N
d) 9.8 N

Answer 1

The compressional force on the fifth lumbar vertebra is related to pressure and is typically associated with lifting heavy objects. Using the formula F=mg, the force for a mass of 80 kg with a gravity of 9.8 m/s^2 is calculated as 784 N.

Step-by-step explanation:

The compressional force on the fifth lumbar vertebra is typically associated with activities such as lifting heavy objects, which can significantly increase the force exerted on the spinal discs. This force is a type of pressure exerted on the vertebra and can lead to severe back injuries if not properly managed. The compressional force is calculated using the formula F=mg, where F is the force, m is the mass, and g is the acceleration due to gravity. In the case of an individual with a mass of 80 kg and using the standard value of 9.8 m/s2 for gravity, the compressional force is 784 N (calculated as 80 kg × 9.8 m/s2). Proper sitting posture and techniques for lifting heavy objects can help to distribute this force more evenly and reduce the risk of injury.
