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
