Question

A human body can only take a maximum sustained deceleration of 500 meters per second squared. how much time in seconds would it take superman to slow down the train from a blistering speed of 100 meters per second?

Answer 1

Superman would take 0.2 seconds to slow down the train from a speed of 100 meters per second.

Step-by-step explanation:

The deceleration of an object is the negative acceleration, which represents the rate at which the object slows down. To calculate the time it takes for Superman to slow down the train, we can use the formula:

t = (v - u) / a

Where:

• t is the time
• v is the final velocity (0 m/s, since the train comes to a stop)
• u is the initial velocity (100 m/s)
• a is the deceleration (-500 m/s²)

Substituting the values into the formula, we get:

t = (0 - 100) / (-500) = 0.2 s

Therefore, it would take Superman 0.2 seconds to slow down the train from a speed of 100 meters per second.
