Answer:

Explanation:
From the question we are told that:
Mass 
Speed 
Mass 
Speed 
Generally the equation for Magnitude of the Third piece is mathematically given by


Where



And


Therefore


The period of the pendulum is given by the following equation
T = 2π * sqrt (L/g)
Where g is the gravity (free fall acceleration)
L is the longitude of the pendulum
T is the period.
We find g.............> (T /2π)^2 = L/g
g = L/(T /2π)^2...........> g = 22.657 m/s^2

I may not be completely sure but compare those 2 things together and you should find your answer.
Answer:
Explanation:
Given:
Initial Velocity, u = 0 km/s (at rest)
Final Velocity, v = 16 km/s
Time taken, t = 3 sec
acceleration, a = (v - u)/t
= (16 - 0)/3
= 5.33 km/s^2
