Question

An athlete covers 100m in 9 sec. Determine his speed. ​

Answer 1

Answer:

Explanation:

Hey sis hope you know the unit m/s

So here both are in equal form so we have to find  the speed

Now,we know speed = distance / speed

=100/9

=11.11111..

However from given the above information it is hard to determine the speed of the athlete at any moment of time.

However, As the person was an athlete so going in accordance with the statistics, the predictable motion of athletes is close to the parabola . i.e athletes generally move with uniform acceleration.

So, In accordance with above observation the relation b/w velocity and time relation can be written as v = (200 /81 )*t

In km / hr = 11 m/s x 18 / 5

40 km / hr
