Question

The increse in veloxity of freely falling object in 1 sec is ??

Answer 1

Answer:

10 m/s

Explanation:

Initial speed = u m/s

Final speed = v m/s

Acceleration due to gravity = g = 10m/s^2

Time = 1 sec

We know, v = u + at

where v is final speed at the end of time t, u is initial speed and a is acceleration of the body.

So, |v - u| = Increase in velocity in time t = |at|

In this case,

|v - u| = |gt|

Increase in velocity = 10 × 1 = 10 m/s
