Superguy is flying at treetop level near Paris when he sees the Eiffel Tower elevator start to fall (the cable snapped). His x-ray vision tells him Lois LaTour is inside. If Superguy is 1.00 km away from the tower, and the elevator falls from a height of 240 m, how long does Superguy have to save Lois, and what must be his average speed

If the elevator falls from a height of 240 meters and Superguy is 1 km away, he will have 6.5 seconds to save Lois, which means that his average speed must be 150 meters per second.

What is the average speed?

The total distance traveled by an object divided by the total time taken is the average speed.

The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.

Given data:

Distance of super guy from the tower = 1.00 km

height(h)= 240 m

From the Newtons' second equation of motion:

[tex]\rm S= ut+\frac{1}{2} at^2 \\\\\ 210 = 0+\frac{10}{2} t^2 \\\\ t= \sqrt 42\\\\t=6.5 \ sec[/tex]

Distance is the foundation as the product the velocity and time;

D=ut

u=d/t

u=1000/t

u=1000/6.5

u=150 m/sec

Hence, he will have 6.5 seconds to save Lois, which means that his average speed must be 150 meters per second.
