Vertical:
(20 m/s) sin(25º) ≈ 8.45 m/s
Horizontal:
(20 m/s) cos(25º) ≈ 18.1 m/s
Objects in contact with each other never get past the electron clouds of the atoms on their surfaces.
Explanation:
Given that,
Mass of a body, m = 1 kg
Force constant, k = 16 N/m
We need to find the angular frequency and the frequency of oscillation.
(a) The angular frequency of a body is given by :

(b) The frequency of oscillation is given by :

Hence, this is the required solution.
Explanation:
Solids have a definite shape and definite volume.
