If you can make it from one end of a football field to the other (100 meters) with an acceleration of 2.2m/s, what would be your top speed if you started from rest?

Respuesta :

Answer:

v = 20.57 m/s

Explanation:

Given that,

Acceleration, a = 2.2 m/s²

Initial speed of the person, u = 0 (at rest)

Distance, s = 100 m

We need to find the top speed. It can be calculated using third equation of motion.

[tex]v^2-u^2=2as[/tex]

v is final speed

[tex]v=\sqrt{2as} \\\\v=\sqrt{2\times 2.2\times 100} \\\\v=20.57\ m/s[/tex]

So, the top speed of the person is 20.57 m/s.
