Question

A stuntman jumps from the roof of a building to the safety net below. How far has the stuntman fallen after 2 seconds?

Answer 1

The height of fall of the stuntman after 2 seconds is 19.6 m.

What is distance traveled by a projectile?

The vertical height of fall of a projectile is the distance traveled by the projectile.

It can also be described as the path of trajectory of the projectile. The vertical motion of a projectile is affected by force of gravity.

Distance traveled by the stuntman during the fall

The height of fall of the stuntman after 2 seconds is calculated as follows;

h = ¹/₂gt²

where;

• t is time of motion of the stuntman
• g is acceleration due to gravity

substitute the given parameters and solve for height attained by the stuntman.

h = ¹/₂(9.8)(2²)

h = 19.6 m

Thus, the height of fall of the stuntman after 2 seconds is 19.6 m.
