Question

If a 230 gram object falls from 2 meters, what is its impulse and velocity upon impact?

Answer 1

1.44Ns

6.3m/s

Explanation:

Given parameters:

Mass of object = 230g = 0.23g

height of fall = 2m

Unknown:

Impulse = ?

velocity on impact = ?

Solution:

We are going to apply one of the equations of motions to solve this problem.

The most appropriate one is:

       V² = U² + 2gH

where V is the final velocity

U is the initial velocity

g is acceleration due to gravity as the body falls with aid of gravity = 9.8m/s²

  H is the height of fall

since the body was initially at rest, U = O

     V² = 2gH

      V = √2 x 9.8 x 2 = 6.3m/s

 Impulse = mass x velocity  = 0.23 x 6.3 = 1.44Ns
