Question

How much height does a freely falling body of mass 10 kg in 2 sec

Answer 1

Answer:

2 sec

10kg=2sec

10-2=10by2.

Answer 2

The height lost during a free fall of a body of mass 10 kg in 2 sec is 19.8 m/s.

Time given $=2 \ sec$

Mass of the body $= 10\ kg$

Objects are falling at the rate of $9.8 m/s^2$ acceleration.

It has been assumed that the body is falling from the rest state that means the body was initially at rest.

Therefore, after two seconds, the object will be traveling $19.6m/s$.

Note:

• If it doesn't always go down at that speed, so we need to calculate the average speed.

• For finding the average speed at which the body was traveling in the free fall and multiply it by the time body traveled at that speed.
• Mass is not relevant assuming no air resistance present in the scenario.
