Since the continents are moving ever so slightly over the years, in couple million years they could all connect again like Pangaea.
Answer:
k = 773.64 N/m
Explanation:
Given:
mass of the pellet, m = 3.56 x 10² kg
Compression in spring, x = 6.61 × 10⁻² m
Height of rise of the pellet, h = 4.83 m
Now, let k be the spring constant
From the concept of conservation of energy, we get
gravitation potential energy acquired by the pellet will be from the energy provided by the spring
thus,

where, g is the acceleration due to the gravity
on substituting the values, we get

or
1.685 = .002178 × k
k = 773.64 N/m
Explanation:
to find the theoretical velocity Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds ,
Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .(s=d/t) and to find the actual velocity use this formulae
h=v0*t+ 1/2 at^2
