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

What is 7.832 rounded to the nearest 10th?
Galina-37 [17]

When rounding you look at the number right after the one you want to round. The tenth place is the one right after the decimal. If the number after it is more than five it goes up by one, it it's less than five it stays the same. So since the number after the 8 is a 3 it stays the same.

The answer is 7.8
