A spring is an object that can be deformed by a force and then return to its original shape after the force is removed.Springs come in a huge variety of different forms, but the simple metal coil spring is probably the most familiar. Springs are an essential part of almost all moderately complex mechanical devices; from ball-point pens to racing car engines.

Explanation:
Given:
x₀ = 0 m
v₀ = 4.2 m/s
t = 11.6 s
a = 2.3 m/s²
Find: x
x = x₀ + v₀ t + ½ at²
x = 0 m + (4.2 m/s) (11.6 s) + ½ (2.3 m/s²) (11.6 s)²
x ≈ 203 m
Round as needed.
The egg was dropped from a height of 24.7 m (free fall motion)
Explanation:
The motion of the egg is a free fall motion (uniformly accelerated motion), so we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the displacement
For the egg in this problem, we have:
u = 0 is the initial velocity
v = 22 m/s is the final velocity
is the acceleration of gravity
s is the vertical displacement (the height from which the egg was dropped)
Solving for s, we find:
